They are murder mysteries that have endured for a generation: three young men brutally killed, hands tied behind their backs, their naked bodies dumped along remote country roads north of Toronto -- their remains only discovered by accident. For nearly four decades there was no way to identify the skeletal remains that were stored in plastic bins at the morgue at the Ontario Coroner's office. Then, in 2006, with advances in forensic science, the Ontario Provincial Police were finally able to identify one of the victims and the hunt for a killer could begin. Now police are hoping to identify the other victims and bring a possible serial killer to justice.
