The Sire of Sorrow / Mélanie Decamps – August 9, 1983 WKT2 #27


Voltigeurs Park campground, August 9, 1983. A mother is absent a few minutes. Upon her return, her daughter, Mélanie Decamps, is missing. Twelve days later, the girl will be found dead, gagged and tied to a tree trunk.

This is Who Killed Theresa?

Today I want to discuss the 1983 murder of 5-year-old Mélanie Decamps. It’s a case that is not unknown in Quebec, in fact, just last summer, marking the 35th anniversary, the Drummondville newspaper, L’Express did an investigative piece about the murder. It is a great long form piece by a journalist I am not familiar with, Stéphane Lévesque.  I only wish there were more stories about cold cases coming out of Quebec like M. Lévesque’s. Today’s story is in part a translation of that piece, including some additional information I’ve uncovered through research, however, what I’m going to ultimately suggest and add to the story has not been featured in any publication.


Tuesday, August 9, 1983 is a beautiful sunny day in Drummondville.

Gilles Thériault, the head of the Sûreté du Québec  station in Drummondville at the time recalls that he, “was at work when the call came in,”

Without delay, patrolmen go to the Voltigeurs Park campground to meet the parents and search for the girl. The search perimeter is expanding and a request for assistance is sent to the district level. The case is quickly handed over to the major crimes unit.

“We had a disappearance or kidnapping. At that time, we did not know it yet, “notes Thériault.

“I did regular checks at the police station,” recalls Gérald Prince, a journalist for  La Tribune newspaper for 27 years.  “That day, I call and I am told that a little girl has disappeared in the Voltigeurs Park. I immediately sent a message to La Tribune.”


Quickly, the SQ team from Trois-Rivières came to the Drummondville substation. Roadblocks are established, divers search the adjacent Saint-François River: they complain that the thick pollution prevents them from examining the river bottom.  A thorough search of the park and the surrounding area are completed. The SQ’s Michel Beaudoin is responsible for the operation.

“First, we met again with Jacqueline Decamps, Melanie’s mother. She explains that she went to the campsite’s convenience store for 15 minutes, leaving her little girl on a swing. When she returned, the eldest of her three children was no longer there. After, she went around the park and the surrounding area with a description of Melanie” recalls Michel Beaudoin.

The day after the disappearance of the six-year-old girl, a witness reports that he saw, on August 9, a little girl holding the hand of a man near the iron bridge that spans the Saint-François River. Based on this observation, a composite photo is established and distributed in the community. Seeing it, a man from Drummondville declares: “This guy, he looks like Michel Déry”.

Michel Beaudoin instructed one of his investigators to meet the 24-year-old man living in Drummondville. The policeman returns to report to the chief investigator: “Forget it, it’s not him. this guy’s a religious nut who speaks of nothing but the Bible.”

Les parents de Mélanie, Jacqueline et Daniel Decamps

In the days following the disappearance, Gilles Thériault has a chance encounter with Michel Déry at the police station in Drummondville. “One day, I remember, I come out of my office, I see a young man sitting there. So I ask: “Is someone taking care of this gentleman? Is he a visitor? Someone coming for a complaint? “Then, a policeman from Nicolet arrives. “It’s our client. It’s an arrest for a car theft. ” He was a young man who looked like a child. He was very small.  He appeared, and he was released. It was Michel Déry, but he was not known to the police at that time.”

On Friday, August 12, a press conference with Daniel and Jacqueline Decamps – Melanie’s parents – is organized. 

Police accept offers from several hypnotists, parapsychologists, and a “radiosthesiste” who sought hints of the little girl using a pendulum, a map and a photo of her.

A Drummondville journalist commented, “As soon as people saw a man with a little girl, they would report it to the police. It had become a real madness. There were even fortunetellers who were pronouncing all kinds of things.  It was beyond reason. It was really a time when there was a lot of stress with people. I felt it”. 

Many calls are routed to police authorities. Mr. Beaudoin quotes as an example: “” The little girl is here, but I want two tickets for Diana Ross and 200 piastres “, reveals Beaudoin in his colorful language. Although not credible at first glance, all of the information collected had to be analyzed. “There were about 100 people working on it. In Drummondville, but also in Montreal, Chibougamau, everywhere across the province.”

Police drain a portion of the St-Francis River in the hunt for traces of Melanie Decamps.Two hydro electric dams were completely closed for several hours so police can get a closer look at the  rocky river bottom. 

Despite the efforts made, there was still no news of Mélanie Decamps. It is the work of an especially  talented investigator who will solve the case: Jean-Paul Prince. On the afternoon of August 20, he was working the streets of Trois-Rivières, Prince was sent to a crime scene in Louiseville, with a colleague from Trois-Rivières. “I was going to take him back to his residence. While going down this road, all of a sudden my colleague points out to me that there is this guy hitchhiking who looks like Michel Déry. He is on the boulevard des Chenaux in Trois-Rivières. We stopped. I opened my window and I identified myself. It was him. “

Jean-Paul Prince invites Michel Déry aboard and a conversation begins, en route to Drummondville. “I talked to  him about girls just to check him out. I told him all kinds of stories. I told him that I had already arrested some people who had committed murder, but that it was not always their fault. If they killed it is because they are sick, “says Prince.

By confiding in him,  Prince tries to coax him. “He told me he was beaten by his parents. He was thrown into the cellar. He told me that he had stayed in Saint-Léonard-d’Aston and that he had remained at one point on the South Shore of Montreal “. Information that does not fall on deaf ears and will be useful later.

Gradually, just before exit 181, Jean-Paul Prince starts talking about Mélanie Decamps. Then, Prince goes to the Voltigeurs Park. There was a broken fence where the team of investigators assumed that the suspect had ducked through with the girl. Arriving in front, it is at this moment that the Prince says: “It is here that the little girl was abducted”. He quickly notices that Déry is nervous. The vice is tightening. Jean-Paul Prince asks Dery directly  if he has kidnapped and killed Melanie Decamps.

“He answered weakly,” Yes, but I did not kill her, I did not kill her! “

The investigator tries to be reassuring by evoking the possibility that she is still alive. Convinced that she was not dead, Jean-Paul Prince brought Michel Déry to the police station.

Other details emerge as Dery is brought to the place where Melanie Decamps would be found. Michel Déry explains to the investigators that from the beginning, he had brought the girl to a park and then brought her home to his apartment at 285 Brock Street where they slept. On this subject, the various discussions with Déry, and the state in which the body was discovered did not lead to the conclusion that there had been sexual assault on the child. According to the 24-year-old man, the next day, August 10, 1983, he wanted to bring Melanie back to the Voltigeurs Park. Seeing the helicopters deployed by the SQ in the sky, he was scared. He entered a wood, near Hemming Road, picked up ribbons used to identify trees and then attached the young Decamps to a tree trunk, a few kilometers south of the Curé Marchand bridge, near the Hydro-Québec towers, about 300 meters from the end of Reid Street.

Due to the darkness, the search cannot continue. The next day, at 5 o’clock in the morning, the search resumes with other police reinforcements and the canine squad. Teams survey the forest sector by sector. The forest is  systematically cordoned in the area indicated by Michel Déry. Because of strong winds that hinder the detection of odors, it is only in the evening, at 9:30 pm, that Mélanie Decamps is found dead tied to a tree trunk with her stockings stuffed down her throat and a banner in her mouth. This information contradicts the story  Déry told that he tied her to “play” with her and then”forgot” where he left her. For Jean-Paul Prince, it is very clear that he tied her up and choked  her. “For sure he strangled her.”

The sight of the bound girl, swollen by days of exposure to heat, provokes reactions of rage and anger.

“For all the police officers who had to work that site, at least 80% of them came back with tears in their eyes. Me, the first “,  states Gilles Thériault.


On August 22, 1983, Michel Déry was brought to the Courthouse of Drummondville under a heavy police escort where he is charged with first degree murder, abduction and kidnapping of Melanie Decamps. The Crown Attorney, Alain Perreault, recommends to Justice Yvon Sirois that the accused undergo a psychiatric examination. Out of this, Déry is judged fit to stand trial. The 24-year-old – through his lawyer – Yves Bolduc, opts for a trail by jury.

The journalist Gérald Prince remembers that people were waiting for him at the entrance of the court and insulted him. Inside, in the court room, Mr. Prince reports that Michel Déry looked vacant.

This absence, this madness, this supposed insanity will be at the heart of the debates chaired by Judge Pierre Pinard. Various specialists, psychiatrists and psychologists will testify on Michel Déry’s ability to distinguish between good and evil. The jury opts for a verdict of non-liability after less than four hours of deliberation, May 28, 1984.

Déry is incarcerated at the Phillipe Pinel Institute for the Criminally Insane in the East end of Montreal. He returns to the news on July 12, 2001 when he manages to trick the guards at the Pinel Institute, and escape. He is quickly found and brought back to the establishment within 24 hours.

Michel Dery’s escape and recapture, 2001

This acquittal for insanity, 35 years later, still leaves a bitter taste among the stakeholders, including Jean Fortier, a reporter with Allo-Police who covered the trial. “I never thought he was crazy. Not crazy enough to put in the fire, He was in between.”

The disappearance and death of Mélanie Decamps deeply affected the population. For both Michel Beaudoin and Jean-Paul Prince, this was the most memorable case in their long careers in law enforcement. “It’s the one that touched me the most. It struck me because she is a child. When you come in contact with the parents as we came in contact, we live their pain. It’s been 35 years and I still think about it, “said Jean-Paul Prince in a low voice full of emotion.


Although Michel Déry is detained, Sûreté du Québec investigators Michel Beaudoin and Jean-Paul Prince continue to investigate. Two years before Melanie Decamps, again in Voltigeurs Park, a little girl went missing, but was soon found.

“The woman who had her child kidnapped did not complain to the police because she was with her lover at the campsite! In filing a complaint, she would have had to say who she was with. Michel Déry, it was he who had kidnapped this little girl, “said Michel Beaudoin without question.

Jean-Paul Prince also remembers meeting Michel Déry at the Sherbrooke jail during the trial. “We have brought out all the unsolved cases in the region and the surrounding area. There is another case that came out in Saint-Hubert: the disappearance of Chantal de Montgayard “.

A discussion lead Dery to confess that it was he who had kidnapped the four-year-old girl when he was a teenager. According to what he told the investigators, on June 4, 1972, he took her to a small wood behind a church in Saint-Hubert, tied her up, but did not kill her. It is a scenario very similar to Melanie Decamps.

M et Mme Claude Montgayard

The experienced police officers  Beaudoin and Prince have obviously validated the veracity of this confession. You should know that in this type of criminal record, there is information that is never communicated to the media. One of these, in the case of Chantal de Montgayard, was the color of her underwear.

Comments Jean-Paul Prince, “He gave us the color of Chantal de Montgayard’s panties and that was correct. When the investigation was carried out at the time, in 1972, he had not been interviewed as a suspect because Déry’s parents had moved to Saint-Léonard-d’Aston a few days later. The body has never been found. Indeed, there was a small woodland behind the church, but it was deforested to build houses. We spoke to the Crown Attorney, but since he was acquitted in one case, it would not have yielded much to accuse him in another. And apart from his statement and his knowledge of the color of the underwear, there was nothing to corroborate. “. Jean-Paul Prince believes that Michel Dery has at least two murders to his credit.


Well, maybe three. If this case sounds familiar to you, it should. Because there are stark similarities with another case from Drummondville, the 1977 disappearance of Claudette Poirier.

We’ve spoken about the Claudette Poirier case before on this podcast, but it would help if I briefly summarized the particulars. I’ve added new information that has not until this point been disclosed:

15-year-old Claudette Poirier lived with her parents at 1190 Monfette in Drummondville. In the summer of 1977 the family decided to do some camping about 7 miles south of Drummondville along chemin Hemming. On July 27th, 1977 the blond haired, 5/’5″ 110 pound girl was  riding her bicycle along 3e Rang de Simpson on her way to a babysitting job on St-Charles boulevard near her home back in Drummondville. 

IMG_0545From that point Claudette disappears. About a week after the disappearance, on August 3rd, 1977, Claudette’s bicycle is found along Rang 3e,  Saint Cyrille,  about 3 miles from her camp site, midway between the camp site and her home in Drummondville.  The bike is off its chain. The man who owns the adjacent property states that the bike – which is in full view at the side of the road – was not there all of the previous week.

The police who investigated the case were the Surete du Quebec forces from Trois Rivieres and Drummondville. After an exhaustive search they are unable to find any trace of Claudette.

On December 8th, 1977 in a chilling article in Quebec’s La Nouvelliste, reporter Yves Champoux suggests that Poirier might have met a similar fate as that of Denise Therrien. In August 1961, 16-year-old Thierren disappeared one morning while disembarking from a bus in Shawinigan. Four years later,  Marcel Bernier, confessed to her murder and agreed to guide the police to the victim’s remains, abandoned in the woods. Some speculated that for the 4 years she was missing, Thierrien was sold into child prostitution. On June 20th, 1962, La Presse featured an article about the “Montreal Paramount Booking” agency, a prostitution ring that would “recruit” 15 and 16 year old girls from Quebec and sell them into sex trafficking in the United States. In the Nouvelliste article, Champoux similarly speculated that Claudette Poirier might have met a similar fate.


9 years after her disappearance on October 9th, 1986, 2 hunters find a skull, other bones and women’s clothing about 15 meters from the road at La Reserve, Saint Lucien about 4 miles from south of the site of Claudette’s disappearance. (I have heard it reported that the bones were charred, as if her remains were burnt). The remains are analyzed by Dr. Andre Lauzon at the SQ medical lab at Parthenais in Montreal and identified as Claudette Poirier. Given the length of time that has passed the cause of death is undetermined.

I made a small map of the Poirier locations, as the story is a little confusing. The map is interactive:  click here and you will be take to the map,  and you can manipulate around the geography:

Screen shot 2016-03-11 at 6.18.53 PM

Basically in the center is where she was camping and last seen, to the left is where she lived and where she was going, to the right is where her bicycle and remains were found. 

So returning to the Melanie Decamps case; what do we find in common here?  To begin with, both victims disappeared while camping in Drummondville, Poirier in 1977 and Decamps in 1983.

In 1977 Michel Dery would have been about 17 or 18, too young to be Poirier’s offender? Hardly. If police suspected him in the 1972 murder of Chantal de Montgayard, when Dery would have been 12 or 13, he would certainly been capable of murdering 15-year-old Claudette Poirier 5 years later.

Where is Poirier’s home? 1190 Rue Monfette is an 8 minute bike ride from the Voltigeurs campground.

Where is 285 Brock street, where Dery had claimed to have slept with Decamps? That’s a 10 minute bike ride from the campground across the Saint Francois river.

And where is Decamps body found? 5 kilometers south of Drummondville at the cross section of Chemin Hemming and Rue Reid. Where was Poirier last seen? 10 kilometers south of Drummondville, riding her bike, also along Chemin Hemming. And where are her remains found? 20 kilometers south, also along Chemin Hemming.

The emphasis on bicycles is important. Note that when Dery was first encountered he had been brought to the station for stealing a car. Later, Jean-Paul Prince picks him up while hitchhiking from Trois Rivieres back to Drummondville. In fact, Dery never appeared to own a vehicle. The story suggests when he needed one, he stole one. On August 27th, 1983 article in The Gazette about Dery makes repeated reference to his use of a bicycle:

“Dery stayed mostly in his apartment, going out only for rides on his bicycle or to get groceries.”

“[Sister Clementine] described him as a “miserable soul,” a loner who liked to ride his bicycle all over Drummondville and the surrounding area, and who was drawn to the silence of the woods.”

I think it’s very possible that Dery used his bicycle to stalk and hunt for prey. When he came upon the right victim, he would steal a car for the purposes of abduction. Or maybe he lured Claudette to follow him on his bicycle? Maybe she thought – slight and five foot tall – that he also was a child.

Michel Dery: “He never had love”, a regrettable article from The Montreal Gazette

I spoke with former Surete du Quebec investigator, Jean-Paul Prince, the officer who cracked the case. Prince is of course now retired and living in Trois-Rivières.  I asked if they ever considered Michel Dery as a suspect in the Claudette Poirier case. Prince stated that he did not recall Poirier’s case.but he imagined they probably ruled Dery out because at that time he was possibly not living in Drummondville, but still with his parents in Saint-Léonard-d’Aston.

Still, Saint-Léonard-d’Aston is only a 25 minute drive from Drummondville, the mid point between Drummondville and Trois Rivieres. Maybe Dery could have been driving by the time he was 17 or 18? If not, maybe in 1977 he had some reason to hitchhike there? In fact the day Jean-Paul Prince picked him up, he was hitchhiking from Saint Leonard-d’Aston going toward Drummondville.  Of maybe he road his bike from Saint Leonard-d’Aston to Drummondville. He was said to have ridden his bike, “all over the Drummondville area”.

What is certain: at some point, something eventually brought him to Drummondville. The question is did he arrive as early as 1977?


CODA: On March 7th, 1979, at the back of their Wednesday edition La Presse discloses that like his sister Claudette, 15-year-old Bruno Poirier has disappeared without a trace:

Bruno Poirier

O Untimely Death! – Ursula Schulze / WKT2 #25

19-year-old Ursula Schulze was abducted at a bus stop in broad daylight the morning of July 13, 1972 in Brossard, Quebec.

The abduction occurred near the girl’s home at 8442 Marie Victorin Blvd.before 8 a.m. when a man dragged her into his car.

The incident was witnessed by many people. “His large hand… he just gripped the girl by the arm and yanked her towards the car,” a witness said. The driver of the car was described as 5’5″ tall, stocky, about 35 years of age with black hair and wearing brown clothing.  Later he was described as between 40 and 50 years of age measuring between 5’6″ and 5’8″ and weighing between 150 and 170 pounds.  Witnesses said he waited for Schulze in the parking lot of La Terrasse Drive-In restaurant. 

The car was described as  “dull red”, with a fastback roofline, possibly a Toyota or a Datsun. 

A witness continued with the following, extremely detailed account of the abduction: 

“It drove up slowly behind the girl, who was standing with her back towards the car. The car stopped in the middle of the road. The driver got out and walked slowly around the back of the car. The girl just had time to turn her head when the guy rushed and grabbed her with his right arm.

“The thing I remember most about the man was his large hand. He just gripped the girl by the arm and yanked her towards the car.

“Opening the door with his other hand he pushed her inside and jumped on her. All I could see was his rear-end sticking out of the car. He must have hit her or something because when he got up and closed the door I couldn’t see the girl.

“He went around the car the same way he approached the girl and drove off. He stayed on the service road as far as I know because I didn’t see him take the entrance to the highway.”

Schulze planned to go shopping for a birthday present for her mother after she got off work at a Place d’Armes office on St. James street where she worked as a file clerk.  Mrs. Schulze described Ursula as impossibly shy. Her parents forced her to take the job as a means of meeting people. 

Schulze was found dead against the wall behind a vacant soap factory in Lapraire  by a truck driver around 4 p.m. on Friday, July 14th. She was found by some bushes near Rang St. Claude, 15 miles from where she had been abducted. One account said Schulze had been strangled. Though there were no signs she had been sexually molested, detectives said her hands and arms bore signs of a severe struggle. Another account said that Schulze had been shot through the back of the head at least twice by a small-calibre weapon.  and there were no signs of struggle at the scene where the body was found.

On Monday, July 17th Gazette reporter Jim Duff reported that an arrest was pending, “The naming of several suspects in the slaying came after a weekend of intensive investigation by detectives from both the Brossard and Quebec Police Forces.” Yet nearly two weeks later QPF detectives admitted that they were no nearer to a solution. “Despite intensive questioning of witnesses and possible suspects, police have been unable to come up with more than a general description of an automobile and the suspect.”

Eight months past. On March 15th, 1973 the following notice appeared in the Montreal Gazette:

The public hearing followed complaints from the parents of Ursula Schulze that the Brossard police did not do everything in their power to locate their daughter. Testimony revealed the father of the murdered girl and another daughter went to the Brossard police station the afternoon of the kidnapping and were told, “We’ll take care of it later.”  It was also determined that the Quebec Police Force / Surete du Quebec was not notified of the abduction until 19 hours after it occurred.

Otto Schulze testified that he went to the office of Brossard Police Chief Marcel Renaud with photos of his daughter the afternoon she disappeared.

Mr. and Mrs. Otto Schulze

“He told me to place the pictures on Blain’s desk (Assistant Director Paul Emile Blain). He said Blain had no time for that right now because he had a more important job to do… that he had a tip on something.”. Chief Renaud told him that Blain would go to his house in about “half-an-hour” for more information on his daughter. “Nobody came to the house until 11:30 p.m. that night.”

Ursula’s sister, Angele who accompanied her father to the police station, continued the testimony. “One of the men at the station suggested that my sister might have made off with some guy. ‘She’s 19 years old and she’s an adult.’ “I told him: ‘Not my sister, I know her.’

Testimony continued:

“…[the duty officer at the time] did not order roadblocks or inform Quebec Provincial Police because this was not “standard practice”. In fact, there were no directives on what standard practice was in such a case.

Other duty officers said they did not know that QPP headquarters was not cut in on the regional network used by municipal forces and thought “somebody else” had informed the QPP directly.

Blain and the officer in charge of criminal investigations, spent the day investigating a report of a robbery by four prison escapees which he told the commission he judged the more serious of the cases.

Both he and Director Renaud thought the QPP had been informed of the kidnapping and were investigating it.”

In April 1973 the commission issued its report. While praising the efforts of on-the-ground constables the report faulted the force director Marcel Renauld and his Assistant Director Paul-Emile Blain for

“”learning nothing” from the incident and failing to instruct force members on how to handle major crimes.”. The report went on to say, “…the “off-hand” manner of force superiors, coupled with the ignorance of force members on procedures and how to use regional communications systems, severely hampered the investigation.”

Brossard Police Chief Renaud called the report “unfair”, “It’s unfortunate they had to judge my department on one isolated incident.” Among the recommendations the Quebec Police Commission recommended that police take special courses in criminal inquires. Renaud stated that is was standard practices to send his men to the Police Academy in Nicolet. “Of the 32 policemen I have I would say only four haven’t gone to the academy yet. But they will be soon.”

The report called on Renaud to ensure that his men put in more than a minimum effort. Renaud replied, “What’s a minimum effort for a guy who works 14 to 18 hours a day?”


Montreal Gazette, Tuesday, July 10th, 1973:

“Slain girl’s parents suing police

The family of Ursula Schulze, the 19-year-old Brossard girl kidnapped and murdered last July, is suing the Brossard police department and the Quebec Police Force.

A suit is expected tomorrow in Superior Court on behalf of Mr. and Mrs. Otto Schulze by lawyer Morris Chaikelson.

Chaikelson said yesterday he is preparing the suit because the Schulzes blame the two forces for the death.”

The Schulzes filed two $100,000 court suits claiming police incompetence in the kidnapping death of their daughter. Defendants in the suits were the Quebec Government, The Quebec Police Force, the town of Brossard, and several of the municipality’s policemen. Each of the Schulzes sought $50,000 for the loss of their daughter in both actions.

No further stories were filed in this matter. It is presumed that the Schulze settled with the Quebec government privately and never went further with legal proceedings.

Despite a good description of Ursula Schulze’s abductor and his vehicle, her murderer has never been apprehended.

“Those who forget the mistakes of history are destined to repeat them.”

All The Devils Are Here – Guylaine Potvin / WKT2 #23

A summary of the April 2000 unsolved murder of Guylaine Potvin in Jonquière, Quebec. We also hear from the second victim in the case, the attacked student from Sainte-Foy in July 2000.

Guylaine potvin


From the Surete du Quebec’s Cold Case Website:

On the morning of April 28, 2000, Guylaine Potvin, a student at the CÉGEP de Jonquière, was found dead in her apartment on rue Panet in Jonquière. She shared the apartment with two girlfriends, students also, who were absent on the night of the events.

Elements of the investigation have shown certain similarities with another file concerning an event in Sainte-Foy in July 2000, in which another student living alone was assaulted in her apartment. The latter, who was left for dead, was more fortunate, she survived.

If you have any information that could help solve this crime, contact the Centrale de l’information criminelle of the Sûreté du Québec at 1 800 659-4264.

Poème écrit par Isabeau, la deuxième victime:

Je me souviens d’une voix de femme : « Reste avec nous ».

Qui est-elle ?

Pourquoi me dit-elle ça ?

 Où suis-je ?

Je me suis ouvert les yeux, une pièce inconnue, l’hôpital, un médecin.

J’ai demandé une seule question : « Qu’est-ce qui s’est passé ? »

Comme seule réponse : « Tu es arrivée avec des policiers, tu leurs parleras plus tard ».

« Non, tout de suite ».

Épuisée, désorientée, j’ai flanché.

Un homme, debout près de moi : « Je suis policier »

« Dis-moi qu’est-ce qui s’est passé ? »

Une réponse, celle que je ne voulais pas : « Je ne le sais pas »

« Comment on va faire pour le savoir ? »

Je me souviens de la feuille de déposition, du crayon, de la tablette improvisée.

Je me souviens de ma question : « Tu veux que j’écrive quoi ? »

J’ai écrit, peu.

Je dormais dans mon lit, dans ma chambre.

Je me souviens de tes mains sur ma gorge.

Je me souviens de ton odeur.

Je me souviens de toi.

Épuisée, désorientée, j’ai flanchée.

J’ai ouvert les yeux.

Une nouvelle pièce : où suis-je ?

Qu’est-ce qui s’est encore passé ?

Devant moi, un policier, le même.

Ses yeux bleus, muets.

Sur la table du lit, une boîte blanche.

« Qu’est-ce qu’il y a dans la boîte ? »

J’ai cru qu’on m’emmenait une réponse,

 Une trousse médico-légale.

Un nouveau policier pour prendre des photos de mes blessures.

Je n’arrive pas à bouger, lui a photographier.

“Place-moi comme tu veux, je ne peux pas t’aider”

“Tu me dis si je te fais mal” ;  j’ai rien dit.

Épuisée, j’ai flanchée.

Examen gynécologique.

Je n’arrive pas à bouger.

Une médecin, enceinte, à genoux sur le pied du lit.

“Ok, vient, on va le faire comme ça”

Elle me tire par les jambes.

Épuisée, j’ai flanchée.

Un appel du policier

« J’ai des collègues qui veulent te parler »

Un espoir : on t’a trouvé.

On m’a montré une photo.

Jeune, belle, souriante.

Tu l’avais choisie elle aussi.

Elle ne se souviendra jamais, elle, de tes mains, de ton odeur.

J’ai compris : on te cherchait déjà.


L’espoir, les jours, les cris, les pleurs.

Des amis questionnés, partis.

Le désespoir, une promesse : « On se boira du porto ».

Des maladresses : « Dans l’autre cas, au moins on a une autopsie »

Des départs, un cold case.

Et la vie, encore la vie.


18 ans déjà.

Je me souviens de chacune des nuits de rage.

Je me souviens d’elle, de chacune de ses photos :

son gâteau d’anniversaire, son chat.

La couleur de son carnet de téléphone, ses gribouillis, son écriture.

Je me souviens des yeux du policier : bleus, muets.

Je me souviens de ma question.

Je me souviens de ton odeur.

Poem written by Isabeau, the second victim:

I remember a woman’s voice: “Stay with us”.
Who is she ?
Why does she tell me that?
 Where am I ?
I opened my eyes, an unknown room, the hospital, a doctor.
I asked only one question: “What happened? “
The only answer: “You came with the police, you will talk to them later”.
“No, right now”
Exhausted, disoriented, I flinched.
A man standing near me: “I am a policeman”
“Tell me what happened? “
One answer, the one I did not want: “I do not know”
“How are we going to find out? “
I remember the witness sheet, the pencil, the improvised tablet.
I remember my question: “Do you want me to write what? “
I wrote, little.
I slept in my bed, in my room.
I remember your hands on my throat.
I remember your smell.
I remember you.
Exhausted, disoriented, I flenched.
I opened my eyes.
A new play: where am I?
What happened again?
In front of me, a policeman, the same.
His blue eyes, dumb.
On the bed table, a white box.
“What’s in the box? “
I thought I was being sent an answer,
 A forensic kit.
A new policeman to take pictures of my wounds.
I cannot move, photographed by him.
“Place me as you want, I can not help you”
“You tell me if I hurt you”; I said nothing.
Exhausted, I flenched.
Gynecological examination.
I can not move.
A doctor, pregnant, kneeling on the foot of the bed.
“Ok, come on, we’ll do it like this”
She pulls me by the legs.
Exhausted, I flenched.
A call from the policeman
“I have colleagues who want to talk to you”
A hope: we found you.
I was shown a picture.
Young, beautiful, smiling.
You had chosen her too.
She will never remember her hands, your smell.
I understood: we were already looking for you.
Hope, days, shouting, crying.
Friends questioned, gone.
Despair, a promise: “We’ll drink port.”
Clumsiness: “In the other case, at least we have an autopsy”
Departures, a cold box.
And life, still life.
18 years old already.
I remember every night of rage.
I remember her, each of her photos:
her birthday cake, her cat.
The color of her phone book, her scribbles, her writing.
I remember the policeman’s eyes: blue, dumb.
I remember my question.
I remember your smell.”

An error by the SQ plunges woman back into the murder of her sister 47 years ago

This is the kind of error I’m always afraid I am going to make. It was my worst fear in those early days with Camirand and Dube. And now it is the SQ that makes this kind of blunder. Unbelievable.
For your information, it took me exactly 45 seconds to do a search on BAnQ’s archives to confirm that Lucie Beaudoin was killed by Henri Vincent. And the Surete du Quebec – with all their resources, with 30 cold-case agents at their disposal – can’t come to the same conclusion over three months?
Here’s a rough translation:
“A blunder from the Sûreté du Québec threw a woman back almost 50 years while her sister was the victim of a villainous murder.
In 1971, Lucie Beaudoin, 19, was murdered. Her body was found in a trunk at the bottom of a flooded quarry in Brossard, Montérégie.
A few months later, Henri Vincent, pleads guilty to manslaughter in connection with the death of the 19-year-old woman. He was sentenced to 9 years in prison.
47 years later, the victim’s sister, Louise Beaudoin, was forced to plunge back into this drama.
Last March, she was contacted by an investigator from the Sûreté du Québec to announce that the murder of her sister was treated as an unresolved case.
“Since that time, every second, every gesture, every minute, it comes back to me,” says the lady met by TVA News.
“I’ve been crying a lot every day since March 23,” she says.
Police even made her sign a form to allow them to place the photo of her sister and a summary of the case on the unsolved crimes section of the SQ website.
Although she said that she had informed the police that a suspect had been convicted in this case, they appeared to not know of it.
Louise Beaudoin says she “doubted her memories” even though she attended court proceedings in 1971.
The Surete du Quebec admitted their mistake, and on May 30, they removed the notice concerning Lucie Beaudoin from her site.
The police said that in the future, things will be different. It seems that before meeting Lucie Beaudoin’s sister, the police only did summary checks.
Nevertheless, until today, no one has apologized for this blunder. Ms. Beaudoin says she is “shocked”, she who is plunged back into painful memories for four months.”

Diane Dery et Mario Corbeil – May 20, 1975 / WKT2 #17


Le 20 mai 1975, vers 20 h 15, Diane Déry, 13 ans, et Mario Corbeil, 15 ans, quittent la résidence de Diane afin de faire une promenade en motocyclette dans un champ situé à proximité du boulevard Rolland-Therrien, à Longueuil. Voyant que les jeunes ne sont pas revenus, des membres de la famille des deux adolescents effectuent des recherches dans le secteur au cours de la soirée et durant la nuit.

Le lendemain matin, vers 7 h 20, les policiers découvrent Diane Déry et Mario Corbeil sans vie dans un boisé situé à l’extrémité du boulevard Rolland-Therrien. L’analyse de la scène démontre que les deux jeunes ont été assassinés.

Allo Police, 5 août 1979 par Jaques Durand

Après 4 ans et sans résolution, le père de Diane Dery, Jaques Dery demande au ministre de la Justice de l’époque, Marc-André Bedard, que l’affaire soit retirée à la police de Longueuil et transférée à la Sûreté du Québec.

En 1975, les Derys habitent au 1145, rue Bizard à Longueuil. Ils ont depuis déménagé à Saint-Célestin (Nicolet). Il travaillait dans une station-service, sa femme tenait la petite cantine à l’intérieur.

Les parents de Maro Corbeil, de M et Mme Maurice et de Françoise Corbeil ont continué de vivre à Longueuil, rue Boucher. L’avocat de Dery dans l’affaire était Guy Houle.

Un récit des événements des 20 et 21 mai 1975

C’était un mardi, une belle journée. Les parents de Mario lui ont donné une petite motocylette en cadeau. Mario a passé de nombreuses heures à en profiter, donnant des tours à sa famille et ses amis. Le dernier trajet était réservé à une petite amie, Diane Dery. Les familles ne les reverraient plus jamais vivant.

Map of Dery / Corbeil murders

Le lendemain, mercredi 21 mai, les corps ont été découverts dans un champ près de l’aéroport de Saint-Hubert. Mario avait été battu, puis abattu six fois avec un pistolet de calibre .22. Diane avait reçu une balle dans la tête avec le même calibre .22. Elle a été agressée sexuellement et son corps a été placé sur celui de Mario. Les corps ont été placés de manière à suggérer qu’ils avaient une relation sexuelle.

L’affaire a été confiée aux détectives Lacombe et Villeneuve de la police de Longueuil. Une douzaine de personnes ont été interrogées.

Après deux ans, M Jacques Dery a pris la décision de tout vendre et de s’installer ailleurs. La famille avait une nouvelle fille, Manon, et ils voulaient commencer une vie meilleure. Il déménage dans un coin de la province, Saint-Célestin (Nicolet). M Dery est devenu propriétaire d’une station-service le long de la route 20. Il a établi une solide clientèle. Il avait un autre projet en tête: faire sortir toute sa famille de Longueuil dès que possible. M Dery a acheté une maison et, au mois d’octobre, sa famille a déménagé dans ce petit village fort et sympathique.

Le travail était dur, il l’obligeait à travailler sept jours par semaine. Mme Dery, non satisfaite de son mari travaillant seule, a décidé de faire fonctionner une petite cantine à l’intérieur de la station-service. Malgré l’arrangement, il y avait toujours deux questions à répondre: QUI et POURQUOI?

M Dery a continué de communiquer avec les enquêteurs à Longueuil. Les enquêteurs ont continué à communiquer le même message: «Nous soupçonnons quelqu’un, mais nous n’avons pas la preuve.”

Voulant en savoir plus, M et Mme Dery ont rencontré le lieutenant-détective Maurice Lauzon, qui était à la tête de l’homicide de Longueuil. Il a informé le Dery qu’il ne connaissait pas le dossier, mais qu’il se mettrait rapidement à l’épreuve. Il a promis de téléphoner régulièrement à la famille pour leur donner des informations sur l’enquête.

«Il n’a jamais répondu, j’ai laissé des messages, mais il n’a jamais rappelé, c’était toujours moi qui devais téléphoner», a déclaré M. Dery qui a ajouté: «Si la police de Longueuil ne peut rien faire pour faire avancer le dossier, pourquoi? ne peuvent-ils pas le livrer à la Sûreté du Québec? Il n’est pas possible que deux jeunes enfants soient tués si près de chez eux, et ils ne peuvent rien trouver, ce n’est pas possible, peut-être que la Surete du Québec ne pourra pas pour trouver quelque chose non plus, mais nous aurions la satisfaction de savoir que nous avons essayé. ”

Au cours de l’entrevue, qui a eu lieu à l’intérieur de la station-service, alors que M Dery vendait des cigarettes aux clients qui allaient et venaient, son fils pompait du gaz et Manon se reposait sur le comptoir. Quand les choses se sont calmées, le garçon est entré et les enfants sont restés près de leurs parents.

Mme Dery, qui était assise à la fenêtre, a dit: «Après quatre ans, je suis venu à l’accepter, je sais maintenant qu’elle ne reviendra jamais, je l’accepte, mais pourquoi quelqu’un ferait-il cela?

Par l’intermédiaire de leur avocat, Guy Houle, les Dery ont demandé au ministre de la Justice du Québec, Marc-André Bedard, de transférer officiellement l’affaire de la police de la ville de Longueuil à la police provinciale, la Sûreté du Québec. Voici le texte de la requête de M Dery envoyé par l’avocat de Dery, Guy Houle:

“Honerable ministre de la Justice:

Considérant les événements du 20 mai 1975. mon enfant Diane Dery, 13 ans, victime d’un assassin, près de chez nous au 1145, rue Bizard à Longueuil;

Considérant que certaines actions et entreprises de la police municipale de Longueuil ont tenté d’élucider cette enquête, mais aucun résultat concret n’a été donné dans l’étude globale de cette affaire;

Considérant que maintenant, depuis plus de quatre ans, nous avions espéré voir des résultats dans ces affaires;

Considérant que la police municipale de Longueuil, malgré tous les efforts dont elle dispose, ne possède peut-être pas tous les outils nécessaires pour mener une enquête et obtenir des résultats;

Considérant surtout que la police municipale de Longueuil ne se spécialise pas dans ce genre d’enquêtes;

Considérant que la Sûreté du Québec a à sa disposition une escouade d’homicides;

C’est pourquoi les gens ont besoin d’être confiants dans les institutions, et certainement dans la protection de la société contre les assassins qui peuvent marcher librement parmi nous.

Nous soumettons cette demande à l’honorable ministre de la Justice de la province que vous prendrez part à cette affaire conjointement avec la police municipale de Longueuil pour faire la lumière au nom de la justice et de la sécurité publique.

Cette lettre a été envoyée au ministre de la Justice le 5 juillet. 1979. Il a également été envoyé à la police de Longueuil, le député de Nicolet-Yamaska, Me Serge Fontaine, et notre collaborateur à Allo Police, Claude Poirier.

Au moment où nous quittions Saint-Célestin, la jeune fille de Dery, qui jusqu’alors n’avait rien dit: «Aujourd’hui, les gens vont tuer pour deux dollars, nous voulons la justice, et tous savent pourquoi ils l’ont fait.

La famille Dery a souffert. Seront-ils heureux un jour quand ils connaîtront les noms des assassins? Nous l’espérons.

La famille Maurice Corbeil a également quitté sa maison de la rue Boucher à Longueuil. Mme Corbeil s’installe à Saint-Félix-de-Kingsey, elle aimerait continuer à aller en Beauce.

M e Corbeil est parvenue à un accord avec l’enquête. De la police, elle dit: “Nous étions soupçonnés d’être méfiants, je veux l’enquête parce que dans des choses comme ça, nous devons trouver les coupables.” Néanmoins, elle essaie de ne pas penser aux choses horribles: «Je ne veux pas de publicité pour mon fils, et je ne veux pas le regarder, pourquoi voudriez-vous de la publicité pour une telle chose?


En novembre 1979, le ministre de la Justice du Québec accepte les demandes des familles et transfère les dossiers à la Sûreté du Québec. Diane Dery et Mario Corbeil sont actuellement répertoriés sur le site Web de la Surete du Québec, toujours en suspens après 43 ans:

Coda: Dans l’article nécrologique de La Presse datant de 1975, on disait que Diane Dery «est morte accidentellement», probablement pour que la famille puisse éviter la honte dans la communauté.

Amazing Journey: Diane Dery and Mario Corbeil – May 20, 1975 / WKT2 #17

On May 20, 1975, at around 8:15 p.m., Diane Déry, age 13, and Mario Corbeil, age 15, left Diane’s home to go for a motorcycle ride in a field near boulevard Rolland-Therrien in Longueuil. Seeing that the young people had not returned, family members of the two teenagers searched the area during the evening and night.

The next morning, at around 7:20 a.m., the police found the bodies of Diane Déry and Mario Corbeil in a wooded area at the end of boulevard Rolland-Therrien and avenue Vaugeulin. The crime scene analysis showed that the two young people were murdered.

From Allo Police, August 5, 1979 by Jaques Durand

After 4 years and no resolution, the father of Diane Dery, Jaques Dery demanded of the then Quebec Justice Minister, Marc-Andre Bedard that the case be taken away from the investigating force, the Longueuil police, and transferred to the Surete du Quebec.

In 1975 the Derys lived at 1145 rue Bizard in Longueuil. They since moved to Saint-Celestin (Nicolet). He worked at a gas station, his wife ran the small cantine inside.

The parents of Maro Corbeil, M and Mne Maurice and Francoise Corbeil continued to live in Longueuil on rue Boucher. The Dery’s attorney in the affair was Guy Houle.

A recounting of events of May 20th and 21st, 1975, from Allo Police

It was a Tuesday, a beautiful day. Mario’s parents gave him a small motocylette as a present.  Mario spent many hours enjoying it, giving rides to his family and friends. The last ride was reserved for a petite ami, Diane Dery. The families would never see them alive again.

The next day, Wednesday, May 21st, the bodies were discovered in a field near the Saint Hubert airport. Mario had been beaten, then shot six times with a 22 caliber pistol. Diane had been shot once in the back of the head with the same caliber pistol, and once in her mid-section. She may have been raped, and her body was placed on top of Mario’s. The bodies were placed in such a way as to suggest they had a sexual relationship.

Map of Dery / Corbeil murders

The case was turned over to lieutenant detectives Lacombe and Villeneuve of the Longueuil police. A dozen persons were interrogated.

After two years, M Jacques Dery made the decision to sell everything and settle elsewhere. The family had a new daughter, Manon, and they wanted to start a better life. He moved to a corner of the province, Saint-Celestin (Nicolet). M Dery became the proprietor of a gas station along route 20. He established a solid clientele. He had another project in mind: getting his entire family out of Longueuil as soon as possible. M Dery bought a house, and in the month of October his family moved to this small, strong and sympathetic village.

The work was hard, it required him to work seven days a week. Not satisfied with her husband working alone, Mme Dery decided to operate a small cantine inside the gas station. Despite the arrangement, there were always two questions that needed answering:  WHO and WHY?

M Dery continued to communicate with investigators back in Longueuil. Investigators continued to communicate the same message, “We suspect someone, but we do not have the proof.”

Wanting to know more, M and Mme Dery met with lieutenant-detective Maurice Lauzon, who was the head of Longueuil homicide. He advised the Dery’s that he was not familiar with the dossier, but he would get up to speed quickly. He promised to telephone the family regularly to give them updates on the investigation.

” He never responded at all. I left messages, but he never called back. It was always me that had to telephone”, said M. Dery who added, “If the Longueuil police can’t do anything to advance the case, why can’t they turn it over to the Surete du Quebec? It’s not possible that two young children are killed so close to their homes, and they can’t find anything. It’s not possible, maybe the Surete du Quebec won’t be able to find anything either, but we’d have the satisfaction to know that we tried.”

During the interview, which took place inside the gas station, as M Dery sold cigarettes to customers coming and going, his son pumped gas and Manon rested on the counter. When things settled down the boy came inside, and the children stayed close to their parents.

Mme Dery, who was sitting in the window, said “After four years I’ve come to accept it I know now that she’s never coming back. I accept that, but why would someone do that?”

Through their attorney, Guy Houle, the Dery’s made a request to the Quebec Justice Minister Marc-Andre Bedard to officially have the case transferred from the City of Longueuil police to the provincial police, the Surete du Quebec.  Here is the text from M Dery’s request sent through the Dery’s attorney, Guy Houle:

“Honerable Minister of Justice:

Considering the events of May 20th, 1975. my child Diane Dery, age 13, a victim of an assassin, close to our home at 1145  rue Bizard in Longueuil;

Considering that certain actions and enterprises by the municipal police of Longueuil were attempted to elucidate this investigation, but no concrete results were given in the total study of this case; 

Considering that now for more than four years we had hoped to see results in these affairs;

Considering that the municipal police of Longueuil, despite all efforts at their disposal, possibly do not possess all the necessary tools to conduct an investigation and achieve results;

Considering above all that the municipal police of Longueuil do not specialize in these types of investigations;

Considering that the Surete du Quebec has at their disposal a homicide squad;

It’s why the people need to be confident in institutions, and certainly in the protection of society against assassins who may walk free among us.

We submit this request to the honorable Minister of Justice of the Province that you will take a hand in this affair jointly with the municipal police of Longueuil to shed a light in the name of justice and public security.”

This letter was sent to the Justice Minister on July 5th. 1979. It was also sent to the Longueuil police, the Deputy of Nicolet-Yamaska, Me Serge Fontaine, and our collaborator at Allo Police, Claude Poirier.

Just as we were leaving Saint-Celestin, the Dery’s young daughter, who up until then had said nothing offered, ” Today people will kill for two dollars;  We want justice, and all of them know why they did it.”

The Dery family has suffered. Will they be happy one day when they know the names of the assassins? We hope so.

The Maurice Corbeil family also left their home on rue Boucher in Longueuil. Mme Corbeil moved to Saint-Felix-de-Kingsey, she would like to continue to go to Beauce.

Mne Corbeil has come to an accord with  the investigation. Of the police she says,  “We were suspected for being suspicious. I want the investigation because in things like this we must find the culprits.”  Nevertheless she tries not to think of the horrible things:  “I don’t want any publicity for my son, and I don’t want to look at it. Why would you want publicity for such a thing?”


In November 1979, the Justice Minister of Quebec agreed to the families’ requests and transferred the cases to the Surete du Quebec. Diane Dery and Mario Corbeil are currently listed on the Surete du Quebec’s cold case website, still unsolved after 43 years:

Coda: In the La Presse obituary from 1975 it was stated that Diane Dery “died accidentally”, most likely so that the family could avoid shame with the community.

Who murdered Murielle Guay? ( 1982 )

The Surete du Quebec’s cold-case posting on Murielle Guay


Conventional wisdom suggests Murielle Guay was butchered by American serial killer William Dean Christensen. Then why is the Surete du Quebec investigating her death as a cold-case?

This much is known. On April 27, 1982, 27-year-old Sylvie Trudel was found decapitated and dismembered in the downtown Montreal apartment of  “Richard Owen.” That same afternoon a pedestrian discovered the dismembered body of Murielle Guay in trash bags in a wooded area of Mille-Îles northwest of Montreal. 

Both murders have long been attributed to American serial killer William Dean Christensen (AKA “Richard Bill Owen”). So why is the Surete du Quebec continuing to pursue Guay’s case as a unresolved murder? (click here to go to their website)

Tracing the origins of misinformation on the internet reveals the following:

At some point between 1995 and 2005 the website posted the following:

the sectioned corpse of Murielle Guay, 26, was found wrapped in trash bags at Mille-Isles, 50 miles northwest of Montreal. Police were initially reluctant to connect the crimes, noting that Trudel’s killer displayed “a certain amount of expertise,” while victim Guay was “really butchered,” but their doubts were resolved by April 29, with murder warrants issued in the name of William Christenson.

On February 25, 2012 the website Coolopolis reported that:

“[Christensen] also murdered Murielle Guay, 26, of Laval, whose body was found dismembered in Mille Iles, northwest of Montreal, decapitated as well, but with less skill, leading authorities to initially believe that it was not the same killer.”

Finally, in his book, Cold North Killers, published March 3, 2013 Lee Mellor writes:

So when did conjecture become internet fact? Difficult to say. When questioned, my friend and colleague Kristian Gravenor – who runs Coolopolis – stated that he was simply reporting what had been reported.

Fact from Fiction

It’s hard not to hold Christensen as a viable suspect. He was released in error from Montreal’s Bordeaux prison just two weeks prior to the murders of Trudel and Guay. Bordeaux is within striking distance from the Bar América on St-Laurent Street in Montreal, where Guay was last seen on April 17, 1982 (contrary to internet reports, Guay was 19, not 24 or 26).


February 17, 1985 La Presse article on William Christensen


I cannot find any news item that definitely links Christensen to the murder of Guay. A 1984 La Presse article state he was “thought to be responsible” for Guay’s murder.  In 1985 La Presse reported that Christensen was “suspected” of Guay’s murder.  In 1989 Le Nouvelliste merely states he was being “investigated” in her murder.  

The Washington Post reported in 1985 that Christensen was “charged in the mutilation deaths of two women in Canada.”, but apparently those charges – at least in the case of Guay – were dropped. Currently Christensen is serving time in the United States for a Pennsylvania murder.

So who killed Murielle Guay? It’s curious. From memory I recall one other case of dismemberment: the 1989 case of Valerie Dalpe. 

It’s also curious – and frustrating – why the Quebec media doesn’t show a greater interest  in these matters. The Surete du Quebec have posted new information on over 60 cases. I’m sure they would welcome the attention, investigation, publication and support of media partners.

Apparently the Surete du Quebec no longer consider William Dean Christensen as a suspect, and are looking for answers.
