Canadian police link Gary Allen Sreri to unsolved murders in Calgary

Canadian police have used DNA evidence to link a deceased convicted U.S. sex offender to the murders of two women and two teenagers nearly 50 years ago and say he may be linked to other unsolved murders or sexual assaults in western Canada.

Eva Dvorak and Patricia “Patsy” McQueen, 14, Melissa Rehorek, 20, and Barbara McLean, 19, were murdered between 1976 and 1977, and their bodies were found in or around Calgary, Alberta.
