S03:E02 - Killer in a Box

In 1986, Toronto and the rest of Canada were stunned by the Alison Parrott case. More than a decade would pass before this tragic case would be solved thanks to the perseverance of the newly formed "Cold Case Squad." In the meantime, the horror of Alison's fate changed many parents' views towards the safety of their children and ushered in an era of educating kids on street smarts. In 1999, due to sophisticated DNA techniques, police finally nabbed the killer Francis Carl Roy and closed one of Toronto's most chilling cases.
