FBI: Body resembles alleged 1976 family killer

The body of a John Doe who bears a "strong resemblance" to a former state department employee accused of the gruesome 1976 sledgehammer murders of his wife, mother and three sons, is being exhumed by the FBI.
Investigators believe the unidentified man who was killed by a hit and run driver in 1981 may well be William Bradford "Brad" Bishop Jr., a mainstay on the FBI's 10 Most Wanted Fugitive's list for years.
He allegedly bludgeoned his family members to death at their home in Bethseda Md. in 1976. Their burned bodies were found in a shallow grave in Columbia N.C..  
They day after they were killed Bishop's last confirmed sighting was at a sporting goods store in Jacksonville N.C..
Two weeks later his station wagon was found in the Great Smoky Mountains National Park, which encompasses more than 500,000 acres.

An avid outdoorsman, Bishop, "could have remained in the North Carolina/Alabama/Tennessee aread for many years without being discovered," according to an affidavit written by FBI agent.  
Investigators will test Bishop's DNA to see if it matches that of the John Doe, but the FBI could not give a timescale for when the results will be known.
