The Ontario Provincial Police have launched a renewed inquiry into a 52-year-old cold case involving the death of teenager Karen Caughlin. Authorities are offering a $50,000 reward for information leading to a breakthrough.

Caughlin vanished on March 15, 1974, after attending a roller skating event in Petrolia. Her body was discovered the following morning in Lambton County. Recent forensic analysis suggests the victim was struck by a vehicle prior to her death.
Investigators urge anyone present at social gatherings near the Rose Gardens rink to come forward. The force is specifically seeking details regarding motor vehicle collisions in the area during that timeframe.
