Decades Pass Without Answers In Canadian Girl's Death

Yvonne Prior has waited more than 35 years for justice since her 16-year-old daughter, Sharron, was killed on Easter Weekend in 1975. The family lived in a quiet section of the city, and the murder seemed to come out of nowhere. Over the years, police in the neighboring city of Longueuil, where the teen's body was found, have tried applying modern investigative techniques. Yet to everyone's frustration, the identity of Sharron's killer remains a mystery.
