Guy Turcotte (born April 21, 1972) is a Canadian convicted murderer and former cardiologist. On February 21, 2009, Turcotte murdered his two children in Piedmont, Quebec, Canada, by stabbing his five-year-old son 27 times and his three-year-old daughter 19 times as they slept in their bedrooms. Background Guy Turcotte, born April 21, 1972, worked with his wife, Isabelle Gaston, at Hôtel-Dieu de Saint-Jérôme, a hospital in Saint-Jérôme, Quebec. Gaston worked as an emergency-room physician and a coroner. He met and began a relationship with Gaston in Québec City in 1999. They moved in together in 2000, but their relationship became hostile to the point of domestic violence from both parties. That violence made Turcotte move out, but he reconciled with Gaston shortly after promising to work on their relationship. Following their reconciliation, Turcotte proposed to Gaston while visiting Mount Washington in New Hampshire; Gaston accepted his proposal. Gilles Turcotte, Guy Turcotte’s brother, said he "was attentive to his children and nieces and nephews.... When Guy is playing with the children, we can see he is having as much fun as them...." In mid-January 2009, shortly before Gaston and Turcotte were planning to leave for a trip to Mexico with their children, Turcotte learned that his wife was having an affair with their personal trainer and friend, Martin Huot. Huot's girlfriend, Patricia Giroux, notified Turcotte of the affair and also provided proof by showing emails between Huot and Gaston. That angered Turcotte, who felt betrayed. He did not cancel the trip, but Turcotte and Gaston decided to separate. Two days after coming home from their trip, Turcotte left the family residence. Gaston and the children stayed in the house, and both parents agreed to share custody. During the separation, conversations between Turcotte and Gaston were often spiteful. On February 8, 2009, Turcotte found out that "the children had been to the Carnaval de Québec with their mother and Huot. The Carnaval reportedly had special meaning to him since he had lived in Quebec City for many years." Turcotte testified that "[a] hammer to the head would have hurt less.... I could not accept that Martin spent time with my children... as if I was being replaced". The next day, a former neighbour told Turcotte that the day he left, Huot had spent the night with his family and had been staying there almost every night for the previous two weeks. Turcotte
