William Bradford Bishop Jr. is accused of bludgeoning his wife, mother, and his three children to death inside their Bethesda home in 1976.
In the case of a 1976 quintuple murder in Montgomery County, the FBI has placed a suspect on its "Top 10 Most Wanted List."
It's one of the most notorious and unresolved murders in Montgomery County history.
William Bradford Bishop Jr. is accused of bludgeoning his wife, mother, and his three children to death inside their Bethesda home in 1976. Authorities say he then drove to North Carolina where he allegedly placed the bodies in a shallow grave and burned them. He was last spotted buying a pair of sneakers in Jacksonville, N.C., and his bloodstained car was later found abandoned in Great Smoky Mountain National Park. Authorities believe Bishop is still alive, could possibly be hiding out in plain sight, and may have even started a new family.
"Brad, you've been living with this on your conscience for 38 years. I am the voice for your family that can no longer speak," says Montgomery County sheriff Darren Popkin. "The time is now for you to contact law enforcement."
Popkin says the renewed push to find Bishop 38 years after the crime occurred comes in part because if he is still alive, Bishop will turn 78 later this year.
"This may the last push that we can do on this. But the family and the victims in this case deserve our attention until we know otherwise."
A forensic artist created a bust of an aged Bishop for today's announcement. Authorities believe it may help with leads on social media.
