Albert DeSalvo, American serial killer known as the Boston Strangler (died 1973)

Albert Henry DeSalvo, also known as the Green Man or the Measuring Man, was an American murderer and rapist who was active in Boston, Massachusetts, in the early 1960s. He is known for having confessed to being the "Boston Strangler," a serial killer who murdered thirteen women in the Boston area between 1962–64. Due to physical evidence, DeSalvo's confession was believed, yet he was only prosecuted in 1967 for a series of unrelated rapes, for which he was convicted and imprisoned until his murder in 1973. DeSalvo's claims to have murdered multiple women was disputed, and debates continued regarding which crimes he truly had committed.

The Boston Strangler is the name given to the murderer of 13 women in Greater Boston during the early 1960s. The crimes were attributed to Albert DeSalvo based on his confession, on details revealed in court during a separate case, and DNA evidence linking him to the final victim.
