A Windsor man found guilty of killing a Huron County couple and a bartender in Windsor more than a decade ago has claimed he was sexually abused.

But it's a claim that was dismissed by the Supreme Court of Canada Thursday.

Jesse Imeson claimed he was abused at a youth treatment centre in Windsor.

Imeson said that led to his behavior as an adult, including the murders he commited in 2007.

The Supreme Court gave no reason for its dismissal.

Imeson pleaded guilty in 2008 to second-degree murder in the killings of Bill and Helene Regier, of Mount Carmel, Ont. and Windsor bartender Carlos Rivera.

Imeson, then 23, was sentenced to life without parole for 25 years.

Rivera was a 25-year-old architectural student. One of his brothers said in his impact statement that "Carlos, in a way, helped take a demon out of society."

Imeson led authorities on an intense eight-day manhunt across the province and into Quebec in 2007 before his arrest.

Shortly after his capture, Imeson told an undercover cop that he had no regrets about killing Rivera, a man he had met just hours before the murder.
