Loudoun County authorities are investigating an apparent murder-suicide of a husband and wife in Sterling Tuesday morning.

The sheriff’s department got a 911 call from a home in the 800 block of South Birch Street, and when deputies arrived, they found a man and a woman had been fatally shot, officials said.

Kraig Troxell, spokesman for the Loudoun County Sheriff’s Department, said investigators believe the man shot the woman then himself. The mother of one of the victims was found unharmed in the home, he said.

The couple appeared to be in their 50s, Troxell said. Investigators have not yet released their identities.
