5x12 - Cold Case Files

A district attorney uses a clever technique--a "John Doe indictment"--to give law enforcement officials the time they need to track down the Schoolgirl Rapist from Rochester, N. Y. And prosecutors reluctantly decide not to prosecute their lead suspect in the rape and murder of a 9-year-old girl because they have only circumstantial evidence. But 12 years later, the cold case squad reopens the case, hoping DNA evidence will prove the supect's guilt.
