A lot of people fought to get Marty's conviction overturned, but one woman really got the process started. Karlene Kovacs was at an Easter dinner party when she says she overheard a piece of critical information. "Somebody had told me that [another guest] was involved. He was there and he pretty much committed the crime and Marty didn't," she says.
Karlene kept what she heard a secret for two years. "I was in shock, and I was in fear for my own life," she says. "I mean, who am I? If he could kill people, and I was pretty much nobody, then maybe he'd [hurt] me." Eventually, Karlene told a private investigator and gave an official statement to Marty's attorneys.
