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.

Popular South Carolina University college senior Samantha Josephson was the pride and joy of her family as she prepared to head off to Drexel Law School with a full scholarship. So, it was unusual when Samantha went missing after a night of socializing at the Five Points bar area in Columbia. Tragically her body was found 24 hours later, with more than a hundred stab wounds. When surveillance footage showed her getting into an Uber in Five Points, police put out an all-points bulletin, and quickly arrested Uber driver Nathaniel Rowlands during a routine traffic stop of a lookalike vehicle. But the case was far from over, as Rowlands claimed someone had stolen his car and he was not the driver in the grainy surveillance photo.
