In River Oaks, Texas, in 1982, the only thing more shocking than Retha Stratton's murder was the fact that Wesley Wayne Miller did it. "He's not the kind of person that if you see him walking down the street, you're gonna cross to the other side of the road for your safety," explains prosecutor Joey Robertson. But as correspondent Susan Spencer reports, Robertson will try to convince a jury at a hearing that if he's simply freed, Miller will kill again. It's a fear that has driven Retha's sister Rona and her best friend Lisa Gabbert to fight for two decades to keep Miller locked up.
