EDMONTON — RCMP say an American sex offender who has since died in prison killed four women and girls in Calgary in the 1970s, and there may be more victims.
Gary Allen Srery was serving a life sentence for sexual assault when he died of natural causes in an Idaho prison in 2011.
Mounties say he already had an extensive criminal record in the United States when he crossed illegally into Canada in the mid-1970s.
The bodies of Eva Dvorak and Patsy McQueen, both 14, were found on a road beneath an overpass west of Calgary on Feb. 15, 1976.
Later that spring, 20-year-old Melissa Rehorek was found dead in a ditch off a gravel road outside the city.
The following year, the body of 19-year Barbara MacLean was discovered outside what was then Calgary's city limits.
Police say a break in the four homicides came when they began comparing DNA of the killer with profiles on ancestry websites, which eventually lead them to a match with Srery.
