A convicted sexual offender with an extensive criminal history in Canada and the U.S. spanning several decades is responsible for the deaths of four young women in Calgary in the 1970s, according to police.
Alberta RCMP say serial killer Gary Allen Srery, who died in 2011 in Idaho, was identified using advancements in DNA technology more than 45 years after the murders.
Police say Srery killed Eva Dvorak and Patricia McQueen, both aged 14, 20 year old Melissa Rehorek, and 19-year-old Barbara MacLean in 1976-77.
Their murders went unsolved until a 2022 tip prompted a review of the historical files. That led police to a suspect hypothesis in 2023, and the creation of a family tree using DNA from distant family members — a police technique known as investigative genetic genealogy.
The U.S.-born Srery, a serial sexual offender who fled to Canada in the mid-1970s, lived in Alberta and British Columbia until the late 1990s. He was deported to the U.S. in 2003.
