Forever Hold Your Peace (S07E02)

An examination of an unusual case in Texas involving the 1988 rape and murder of a pizza-parlor employee. After a suspect confessed, and he and an alleged accomplice were imprisoned, the case was considered closed. Eight years later, however, another man confessed to the same crime – and DNA evidence cleared the first suspect while implicating that the second was, in fact, guilty. (TruTV)
