Who Killed Toni Heartstring

Marty Tankleff was only a teenager when he was convicted of murdering his parents. He spent more than half his life in remote New York state prisons, a far cry from his privileged childhood on New York's Long Island. Marty initially confessed, but quickly recanted. He fought for years for his innocence, especially as new witnesses surfaced that could potentially exonerate him. Correspondent Erin Moriarty, who has covered this case for years, reports on this rollercoaster of a legal case.
