Janet Walsh was 23 years old when she was found murdered in her Monaca, Pennsylvania home in 1979. Walsh was strangled. The night before her death, she was at a nightclub with a couple of girlfriends. The next morning Walsh didn’t show up for work. Police had five suspects, but they couldn’t put a finger on any of them. There wasn’t enough evidence. In 2010, the Pennsylvania Cold Case Unit looked again at the investigation. They found DNA in semen on the back of Walsh's nightshirt.
In 2013, former Bridgewater councilman Gregory Scott Hopkins, now 69, was found guilty of third-degree murder. Hopkins admitted to having an affair with Walsh but denied killing her. In 2014, he was sentenced to 8 to 16 years in prison. 48 Hours will feature the story on Saturday, May 16 at 10pm on CBS.
