25-year-old Ashley Biggs, a single mom and pizza delivery driver, was murdered on a late-night run for Dominos. Police arrested her former boyfriend Chad Cobb. For eight years, Cobb refused to tell police who had helped him lure Ashley to her death, protecting his then-wife, Erica Stefanko. But once he learned that Erica had become romantically involved with his best friend and that she was allegedly abusing his daughter, Cobb revealed Erica's role in the murder, and she was now facing a criminal charge for murder. Erica's defense lawyer argued it was a case of revenge, with no forensic evidence to tie her to the scene. But in a surprising twist, Chad produced damning new evidence to back up his story.
