Serial child killer David Threinen’s reign of terror

Terror took root in central Saskatchewan on this day 40 years ago. On June 15, 1975, two children, 12-year-old Dahrlyne Cranfield and Robert Grubesic (inset), 9, disappeared while riding their bicycles along the South Saskatchewan River in Saskatoon. Roughly a month later, Samantha Turner, 8, and Cathy Scott, 7, disappeared. Parents kept their children home behind locked doors. Finally, a tip led police to David Threinen, a truck driver with a history of sex attacks against children. He confessed and led officers to the bodies of his victims. He had strangled them and dumped them in two remote locations outside Saskatoon. A psychiatric report revealed in parole records (read document after the jump) would later describe Threinen as “a cold, amoral individual who felt compelled to offend sexually against children and who experienced no remorse for his victims even when he killed them.”
