Guy Turcotte killings

Background and Marital Breakdown

Guy Turcotte was born on April 21, 1972, and worked as a cardiologist at Hôtel-Dieu de Saint-Jérôme hospital alongside his wife, emergency physician and coroner Isabelle Gaston. The couple began their relationship in Quebec City in 1999 and moved in together in 2000. Their relationship was marked by periods of hostility and mutual domestic violence, leading to a temporary separation before they reconciled and became engaged during a visit to Mount Washington in New Hampshire. In mid-January 2009, just before a planned family trip to Mexico, Turcotte learned from his personal trainer's girlfriend, Patricia Giroux, that Gaston was having an affair with their mutual friend and trainer, Martin Huot, and she provided proof via emails.

The couple proceeded with the vacation but decided to separate immediately upon their return, with Turcotte moving out of the family home in Piedmont while agreeing to shared custody of their children, Olivier and Anne-Sophie. The separation period was acrimonious, with Turcotte growing increasingly distressed by Gaston's new relationship. On February 8, 2009, he discovered that Gaston had taken the children to the Carnaval de Québec with Huot, an event that held personal significance for Turcotte from his years living in the city, and he later testified that this information felt like 'a hammer to the head'. The next day, a neighbour informed him that Huot had been staying at the family home almost nightly since Turcotte's departure, which Turcotte said made him 'flip'.

A physical confrontation occurred on February 10 when Turcotte went to the house to retrieve his son's sweater and found Huot in the kitchen. Turcotte punched Huot in the face, accusing him of stealing his wife and betraying their friendship. On February 20, 2009, Gaston told Turcotte she had changed the locks, consulted a lawyer, and warned she could seek full custody and even change the children's names. This left Turcotte terrified of losing them and prompted him to reply that if she wanted war, she would get it.

The Murders and Immediate Aftermath

On the night of February 20, 2009, after putting his children to bed at his residence, Turcotte felt dejected and began to cry. He read old emails from Gaston that further hurt him and searched the internet for suicide methods, expressing suicidal thoughts to his mother, who subsequently called 911. In the early hours of February 21, police officers responding to the wellness check entered Turcotte's home and discovered the bodies of his two children. Turcotte was found under his bed, covered in vomit and blood, and told police he had consumed windshield washer fluid in an attempt to die and that he had hurt his children.

In his later testimony, Turcotte recalled disordered scenes of the attacks, stating he was standing in his son's room with a knife, panicked when his son cried out and moved away, and stabbed him more, and he reported a similar memory with respect to his daughter. He described seeing himself in the bathroom with blood on his hands after drinking the fluid, looking for the knife to stab himself in the heart but being unable to find it. The autopsy revealed Olivier had been stabbed 27 times and Anne-Sophie 19 times as they slept in their bedrooms. The murders shocked Canada and ignited debate over mental disorder defences and the criminal justice system.

• February 20, 2009: Turcotte puts his children to bed, reads emails, and searches online for suicide techniques.
• Late evening: Turcotte expresses suicidal thoughts to his mother, who places a call to 911.
• Morning of February 21, 2009: Two police officers enter the home on a wellness check.
• Discovery: Officers find the bodies of five-year-old Olivier and three-year-old Anne-Sophie.
• Location of Turcotte: He is discovered under his bed, covered in vomit and blood.
• Immediate statement: Turcotte tells police he drank windshield washer fluid and wanted to die.
• Autopsy results: Olivier sustained 27 stab wounds. Anne-Sophie sustained 19 stab wounds.

The Parole Board of Canada later cited the exceptional gravity and violent nature of his crimes. This brutality was heavily emphasized during his sentencing and parole hearings. The combined total of 46 stab wounds was a central element in the case. The case highlighted the extreme violence that can occur in domestic settings.

First Trial and Not Criminally Responsible Verdict

Turcotte was charged with two counts of first-degree murder for the deaths of his children. His trial began on April 12, 2011, in the Superior Court of Quebec, District of Terrebonne, presided over by Justice Marc David. The defence did not dispute that Turcotte caused the deaths but argued he was not criminally responsible due to a mental disorder. Turcotte's legal team contended that at the time of the killings, he was suffering from an adjustment disorder with anxiety and depressive moods, compounded by a suicidal crisis and methanol intoxication from the windshield washer fluid, which rendered him incapable of appreciating the nature of his acts or knowing they were wrong.

On July 5, 2011, the jury returned a verdict of not criminally responsible on account of mental disorder, and Turcotte was subsequently committed to the Institut Philippe-Pinel de Montréal, a secure psychiatric facility, for treatment and assessment. The verdict was met with public outrage and scrutiny, particularly from victims' rights advocates and Gaston, who felt justice had not been served for her children. Following the verdict, Turcotte underwent psychiatric treatment, and in 2012, testifying before a mental health review board to determine if he should be released, Turcotte stated he felt less shame and guilt, had more self-esteem, and was ready for release, claiming he was not a danger to anyone. He remained at the Institut Philippe-Pinel for a total of 46 months of psychiatric care before being deemed fit for release from the mental institution, though he remained in custody awaiting the appeal process.

The prosecution successfully appealed the verdict on the grounds that the trial judge had erred in law, mainly with respect to the issue of self-induced methanol intoxication in conjunction with a mental disorder. The appellate court found that Justice Marc David failed to properly guide the jury on how to distinguish whether Turcotte's incapacity stemmed from a mental disorder or from self-induced intoxication. This legal error necessitated a new trial. The appeal decision was a significant legal development in the case.

Appeal, Second Trial, and Conviction

The Crown successfully appealed the verdict, arguing that the trial judge had erred in his instructions to the jury regarding the defence of mental disorder when combined with evidence of self-induced intoxication. Turcotte's lawyer, Pierre Poupart, announced in 2014 that he wanted to go to the Supreme Court of Canada to challenge the appeals court ruling, but the application for leave to appeal (file 35675) was ultimately denied. After spending 46 months in psychiatric care, Turcotte was deemed fit for release from the institution but remained detained awaiting his new trial, and he was released on a $100,000 bail on September 12, 2014. His second trial began in September 2015.

In December 2015, an 11-person jury found him guilty of two counts of second-degree murder. On January 15, 2016, he was sentenced to life in prison with no chance of parole for 17 years. The mandatory sentence for murder in Canada is life imprisonment. The judge set the parole ineligibility period at the maximum of 17 years for second degree murder.

1. July 5, 2011: Jury renders verdict of not criminally responsible due to mental disorder.
2. 2014: Turcotte's application for leave to appeal to the Supreme Court of Canada (file 35675) is denied.
3. September 12, 2014: Turcotte is released on $100,000 bail pending his new trial.
4. September 2015: The second trial begins.
5. December 5, 2015: An 11-person jury convicts Turcotte of two counts of second-degree murder.
6. January 15, 2016: Sentencing: life imprisonment with 17 years of parole ineligibility.

The judicial process lasted for many years. Isabelle Gaston, the children's mother, described this lengthy process as repeatedly revictimizing her. She stated she had been disappointed countless times by the system. The case highlighted the challenges juries face in disentangling mental disorder and intoxication factors.

Incarceration and Parole Board Hearings

Turcotte became eligible to apply for escorted temporary absences (ETAs) earlier in his sentence, which allow an inmate to leave a correctional institution for a limited time accompanied by staff. The board heard from Turcotte, who stated he had been in an 'egocentric suicidal rage' the night of the murders following months of stress and depression but now had better emotional control, and he claimed that what pushed him over the edge was reading emails between Gaston and her partner. The board acknowledged his progress, model inmate behaviour, and a recent psychiatric evaluation indicating a low risk of recidivism. Isabelle Gaston delivered a powerful victim impact statement opposing the request, detailing her enduring pain, post-traumatic stress disorder, financial suffering, and an inability to grieve properly, and she stated she did not want her third child to feel in danger.

The Parole Board denied Turcotte's request, citing the exceptional gravity and violent nature of the crimes and the deep impact the murders continued to have on the victims' mother, concluding it was too soon to grant such a privilege. Victim rights advocate Darlene Ryan, who attended the hearing, called the request a slap in the face to Gaston. Ryan noted the irony that Gaston's children can no longer visit their parents while Turcotte sought to visit his. The Parole Board of Canada's decision showed the weight given to victim impact in such serious cases.

• Turcotte's stated motive for the 2009 murders: He did not want his children to find him dead and decided 'they must come with me.'
• Trigger cited: Reading emails between Gaston and her partner pushed him 'over the edge.'
• Turcotte's self-assessment: He claimed he 'didn't use judgement' and 'only saw my pain.'
• Board's positive findings: Acknowledged low risk to re-offend, shows remorse, and visits could aid rehabilitation.
• Gaston's impact statement: She stated, 'We never get over the murder of our children,' and described 'living with pain that never ends.'
• Gaston's core demand: She wants Turcotte 'to take responsibility from A to Z' and recognize the irreparable harm.
• Board's decisive reasons for denial: Exceptional gravity of crime, violent nature, and impact on the victim's mother.
• Practical detail of request: The escorted leave was for up to seven hours to visit his parents.

Legal and Cultural Impact

The Guy Turcotte case has had a significant impact on Canadian legal discourse and popular culture. Legally, the appeal and subsequent Supreme Court of Canada application centred on complex questions regarding the defence of not criminally responsible, particularly when a mental disorder is intertwined with self-induced intoxication. The Supreme Court case summary framed the issues around whether the Court of Appeal erred in considering the intoxication self-induced and whether it erred in ordering a new trial on first-degree murder counts after the jury had decided on incapacity. The case highlighted the challenges juries face in disentangling these factors and prompted ongoing debate about the thresholds for criminal responsibility in Canada.

In popular culture, the murders inspired the 2014 seventeen-minute short film Will of Fortune by Canadian director Chloë Bellande, which premiered at the Cannes Film Festival and drew parallels between Turcotte's case and that of Susan Wright, who stabbed her husband nearly 200 times in Texas. The Guy Turcotte case became a dark cultural reference. In 2023, Montreal rapper Enima made a threatening statement in Spain alluding to his ex-partner and son. He stated, in French, that he would make a Guy Turcotte of himself if anyone moved.

The case also spurred commentary from victim rights advocates like Darlene Ryan. Ryan, whose stepdaughter was murdered in 2006, stated the system victimizes victims over and over again. She referenced her own experience of giving ten victim impact statements. The case remains a reference point in discussions on domestic violence and victim advocacy in Canada.

Key Figures and Ongoing Proceedings

The case involves several key individuals whose lives were irrevocably changed by the events of February 2009. Isabelle Gaston, the children's mother and Turcotte's ex-wife, has become a public advocate for victims, persistently engaging with the parole process to represent her children's interests, and she has a third child from a subsequent relationship. Turcotte's defence was led by lawyer Pierre Poupart during the trials and appeals, while the prosecution was handled by Crown attorneys who successfully argued for a new trial on the grounds of judicial error. Justice Marc David of the Quebec Superior Court presided over both trials and delivered the life sentence, and the initial appeal court decision criticized his instructions to the jury regarding intoxication and mental disorder.

Other individuals involved include Martin Huot, the personal trainer whose affair with Gaston precipitated the marital crisis, and Patricia Giroux, Huot's girlfriend who informed Turcotte of the affair and provided email proof. Gilles Turcotte, Guy's brother, provided character testimony before the murders, describing him as attentive and playful with children and nieces and nephews. Turcotte remains incarcerated and eligible for parole after serving 17 years of his life sentence. His case continues to be cited in legal discussions concerning mental disorder defences and domestic homicide.

Questions about Guy Turcotte killings

What were the names and ages of Guy Turcotte's children?

Guy Turcotte's victims were his two young children. His son was Olivier Turcotte, who was five years old at the time of his death. His daughter was Anne-Sophie Turcotte, who was three years old. The murders occurred on February 21, 2009, in the family home in Piedmont, Quebec. Both children were stabbed multiple times as they slept in their bedrooms, with Olivier suffering 27 wounds and Anne-Sophie suffering 19.

Why was Guy Turcotte's first murder verdict overturned?

The initial 2011 verdict of not criminally responsible due to a mental disorder was overturned on appeal by the Quebec Court of Appeal. The appellate court found that the trial judge, Justice Marc David, made an error in law in his instructions to the jury. Specifically, he failed to properly guide the jury on how to distinguish whether Turcotte's incapacity stemmed from a mental disorder or from self-induced methanol intoxication from drinking windshield washer fluid. This legal error necessitated a new trial.

What sentence did Guy Turcotte ultimately receive?

Guy Turcotte was sentenced to life in prison with no chance of parole for 17 years. This sentence was imposed on January 15, 2016, following his conviction in December 2015 for the second degree murder of his two children. The mandatory sentence for murder in Canada is life imprisonment. The judge set the parole ineligibility period at the maximum of 17 years for second degree murder.

Has Guy Turcotte been granted any release from prison?

Guy Turcotte has not been granted release from prison. The Parole Board of Canada denied his request for an escorted temporary absence, stating his absence was not desirable given the exceptional gravity and violent nature of his crimes. It considered the deep impact the murders had on his ex wife Isabelle Gaston. Turcotte had requested a supervised outing of up to seven hours to visit his parents. He remains incarcerated serving a life sentence with parole ineligibility for 17 years from his 2016 sentencing.

What was Isabelle Gaston's role in the parole hearing?

Isabelle Gaston, the children's mother and Turcotte's ex wife, delivered a victim impact statement at the parole hearing. She told the board she is living with pain that never ends and detailed suffering from PTSD and fear. Gaston expressed she did not want her third child to feel in danger if Turcotte was granted temporary leave. She stated she wanted Turcotte to take full responsibility and recognize the irreparable harm he caused. The parole board cited the impact on Gaston as a key reason for denying Turcotte's request for an escorted temporary absence from prison.

When will Guy Turcotte be eligible for parole?

Guy Turcotte will be eligible for parole after serving 17 years of his life sentence. He may apply for day parole six months before that full parole eligibility date. Any earlier release would require a granted escorted temporary absence for specific purposes, which has been denied. The parole board evaluates such requests based on the offender's conduct, risk to reoffend, and release plan, but Turcotte's initial request was rejected due to the gravity of his crimes.
