Albert DeSalvo, who confessed to being the Boston Strangler in 1967, has been linked by DNA evidence to the 1964 slaying of Mary Sullivan, The Boston Globe reported.
Authorities excavated DeSalvo's remains from a cemetery on July 12 in an effort to resolve the case.
"I hope this brings some measure of finality to Mary Sullivan's family," Attorney General Martha Coakley said in a joint statement with the Suffolk district attorney and Boston police. "This leaves no doubt that Albert DeSalvo was responsible for the brutal murder of Mary Sullivan, and most likely that he was responsible for the horrific murders of the other women he confessed to killing."
DeSalvo confessed to 11 murders following his capture in 1967. However, his confession was ruled inadmissible in court and he was never charged in the Strangler cases. He was instead convicted on unrelated rape charges and sentenced to life in prison. He was killed by another inmate in 1973.
