PEABODY, Mass. (AP) — Investigators have unearthed the remains of a man who once confessed to being the Boston Strangler in a bid to use forensic evidence to connect him to the death of a woman believed to be the serial killer's last victim.
A bevy of law enforcement officials surrounded Albert DeSalvo's grave on a grassy plot near a lake for Friday's exhumation, which lasted about an hour.
DeSalvo admitting killing Mary Sullivan and 10 other women in the Boston area between 1962 and 1964 in a series of slayings that became known as the Boston Strangler case. But he recanted in 1973 before dying in prison, where he was serving a life sentence for other crimes.
Authorities said Friday that they would take DeSalvo's remains from Peabody to the medical examiner's office in nearby Boston, where they'd take tissue or bone samples for DNA testing.
Police and prosecutors said on Thursday that, for the first time, they had DNA evidence linking DeSalvo to Sullivan's death.
With a search warrant, authorities dug up DeSalvo's remains because testing of DNA from the scene of Sullivan's rape and murder had produced a match with him that excluded 99.9 percent of suspects. They are after a perfect match.
The breakthrough happened after scientific advances that authorities said became possible only recently. Police secretly followed DeSalvo's nephew to collect DNA from a discarded water bottle to help make the connection.
Sullivan grew up on Cape Cod before moving to Boston when she was 19. A few days later, she was dead — raped and strangled in her new apartment.
Sullivan's nephew, Casey Sherman, spent part of his life believing in DeSalvo's innocence. But he said Thursday that the latest evidence points a different way.
Suffolk District Attorney Daniel Conley said the new evidence applies only to Sullivan's homicide and not to the other Strangler-linked killings. He said some law enforcement officials still disagree about whether one person committed all 11 slayings.
