The Alberta RCMP has revealed a significant breakthrough in a series of unsolved murders from the 1970s, linking an American serial killer Gary Allen Srery to the deaths of four young women in Calgary. Gary Allen Srery, who died in an Idaho prison in 2011, has been identified as the perpetrator.

DNA Evidence Unravels Decades-Old Mystery

At a recent news conference in Edmonton, RCMP officials announced that DNA found on two of the victims was crucial in identifying Srery. Using genealogical techniques from Convergence Investigative Genetic Genealogy (IGG), a family tree was constructed from the DNA, ultimately leading to Srery's identification. This development came despite Srery never being a suspect during the initial investigation.

Gary Allen Srery's Elusive Life Explained

Gary Allen Srery, born in 1942, had a history of sexual crimes. He fled the United States in 1974 after posting bail for a rape charge in California, later settling in Calgary under various aliases. During his time in Canada, he led a transient lifestyle, working intermittently and frequently changing his appearance, his residence and what cars he owned. He was known to use names such as Willy Blackman and Rex Edward Long.
