Investigators say the FBI will use DNA from a decades-old cigarette butt in its quest to determine whether a body exhumed from an Alabama grave is one of its top 10 most-wanted fugitives.
Scottsboro police Lt. Scott Matthews said Friday the cigarette butt was collected at some point as authorities investigated William Bradford "Brad" Bishop Jr. Bishop was accused of using a sledgehammer to kill his wife, mother and three sons in their Bethesda, Maryland, home in 1976. He vanished soon after.
FBI spokesman Paul Daymond says a tip from an Alabama man proved critical in the agency's ongoing effort to finally find Bishop Jr.
On Thursday, the body of an unknown hitchhiker who had been killed by a vehicle in 1981 was exhumed from a grave in Scottsboro, Alabama.
