FBI now looking in Southern California for 'Most Wanted' killer William Bradford Bishop

(AP) - The FBI says they are now looking toward Southern California for traces of "Most Wanted" killer William Bradford Bishop.

Bishop, a diplomat, is accused of bludgeoning his mother, wife and three sons to death with a hammer in 1976 in their home in Maryland, just outside of D.C. He allegedly burned and buried the bodies in North Carolina.

Agents are now taking a second look at the case, as Bishop was officially added to the Most Wanted list earlier this month. In doing so, the agency released a number of photos and a bust of what Bishop might look like today, at age 77.

Friday, the FBI announced that Bishop has Southern California roots.

Bishop was born in Pasadena and still has associations in the area. He was also known to have an affinity for the Sierra Nevada, authorities said.
