Albert De Salvo was better known as who

Boston Strangler
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 from 1962 to 1964. DeSalvo was not imprisoned for these murders, however, but for a series of rapes.

His murder confession has been disputed and debate continues as to which crimes DeSalvo had actually committed.

In July 2013, a DNA match between seminal fluid found at the scene of the rape and murder of Mary Sullivan and DNA obtained from DeSalvo's nephew linked DeSalvo to that crime and excluded 99.9 percent of the remaining population.

Authorities exhumed DeSalvo's remains later that month and confirmed the DNA match.
