Remains of strangler exhumed

PHILADELPHIA -- An autopsy began Saturday on the exhumed remains of the confessed Boston Strangler in an attempt to identify his killer and possibly prove his innocence in the notorious murders.

The body of Albert DeSalvo was exhumed from his Massachusetts grave Friday and transported to a forensic laboratory at York College in central Pennsylvania.

Along with their curiosity about his killer, the families of DeSalvo and Mary Sullivan, believed to be the last of the strangler's 13 victims, don't believe DeSalvo was the strangler. They're seeking DNA and forensic evidence to make their case.
