Desfossés was arrested and detained while driving on Autoroute 40 near Louiseville on 24 March 1992 after U.S. authorities requested his extradition on several charges, including the murder of David Singer and the attempted murder of Michael Foti. He was held at the Parthenais Detention Centre in Montreal while challenging his extradition to Florida, which was approved in September 1997 after the Supreme Court of Canada refused to hear his appeal. On 29 May 1998, Desfossés pleaded no contest to the charge of non-premeditated murder and was sentenced to twelve years in prison. His lawyer John Howes explained that Desfossés "took this deal because he wanted to be home in Canada on time for his 30th wedding anniversary next summer". Howes estimated that Desfossés would be paroled within fourteen months because he had already spent seven years in custody while fighting his extradition. In November 1998, the Royal Canadian Mounted Police (RCMP) accused Desfossés, Roger Forgues, Pierre "Panache" Tremblay, and four others of importing 210 kilograms of cocaine into Quebec in early 1987. The Canadian government decided against perusing the extradition of Desfossés, the alleged leader of the drug ring, however. He was transferred to a Canadian penitentiary before being released on parole in early 2000.L'ex-boss du tueur à gages Gérald Gallant veut une peine réduite Éric Thibault, Le Journal de Montréal (8 March 2016)
