Serial killer responsible for 2 unsolved murders of young women in Pittsburgh area, police say

For about five decades, two Washington County families have been without answers as their loved ones' killer was still out there. Now state police have given them some closure and believe the suspect may have been a serial killer behind more deaths. In 1976, 21-year-old Susan Rush left a Washington County shopping center to head to a Thanksgiving Eve dinner. She never made it and was found dead in the trunk of her car on North Avenue. A few months later, in May 1977, 18-year-old Brenda Ritter left her boyfriend's house and never made it home. She was found dead on a hillside near Roupe Road in South Strabane.Brenda Ritter (left) and Susan Rush (right) (Photos: Pennsylvania State Police) "These cases never go away," said Cpl.
