The Boston Strangler 1996 Documentary

Albert Henry DeSalvo (September 3, 1931 – November 25, 1973) was a criminal in Boston, Massachusetts, who confessed to being the "Boston Strangler", the murderer of thirteen women in the Boston area. DeSalvo was not imprisoned for these murders, however, but for a series of rapes. His murder confession has been disputed, and debate continues regarding which crimes DeSalvo actually committed.
