William Bradford Bishop, Jr., wanted for the brutal murders of his wife, mother, and three sons in Maryland nearly four decades ago, has been named to the Ten Most Wanted Fugitives list.

A reward of up to $100,000 is being offered for information leading directly to the arrest of Bishop, a highly intelligent former U.S. Department of State employee who investigators believe may be hiding in plain sight.
