Over an 18-month period from 1962 to 1964, the city of Boston was terrorized by a serial killer, the infamous "Boston Strangler." But in 1964, Albert DeSalvo confessed to the brutal killings of 13 women, and authorities and the city at large breathed a collective sigh of relief, believing the killer was finally behind bars. When he confessed, DeSalvo was a patient in a mental hospital, and his confession could not be used against him. With no evidence linking him to any of the 13 murders, DeSalvo was convicted of unrelated crimes and was sentenced to life in prison. Now, 36 years later, 48 Hours reports that some investigators, as well as the family of one victim, are not sure that DeSalvo was the killer. They believe DeSalvo lied in his confession, and they want to force the state to open the case.
