Authorities have arrived at the Massachusetts cemetery where the remains of the Boston Strangler are expected to be excavated.
A spokesman for the Suffolk District Attorney's office says Albert DeSalvo's casket is expected to be exhumed Friday afternoon in Peabody.
A spokesman says DeSalvo's casket will be taken to the medical examiner, where tissue or bone samples will be taken.
It's part of a process that Suffolk DA Dan Conley believes will tie DeSalvo to the death of Mary Sullivan, possibly the Strangler's last victim. Already, DNA from Sullivan has been matched to a member of DeSalvo's family.
Eleven women were killed in the Boston Strangler slayings in the 1960s. DeSalvo confessed, but later recanted and was never convicted in the slayings.
