Dennis Wise, an alleged Baltimore hit man, was released from prison this summer under the Unger ruling. Wise has maintained his innocence. In March last year, a 1966 murder conviction was vacated against Charles Scott. He had served 50 years of his life sentence for murder. Baltimore prosecutors have struck Unger deals with more than 100 prisoners, saying it's difficult to retry old cases after memories fade, evidence is missing, and witnesses have died.
