Ohio v. Erica Stefanko. In a tale of jealousy, betrayal and revenge, 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, saying he killed her over a bitter custody dispute involving their seven-year old daughter. For eight years, Cobb had 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.
