A former Fairfax County police officer from Annandale and his teenage daughter are dead in an apparent murder-suicide, Fairfax County police said.

John Jackson, 40, and his daughter, Alexis Jackson, 13, were found dead of gunshot wounds early Tuesday inside a black sport-utility vehicle parked in the driveway of a house in the 3800 block of Forest Grove Drive, according to police spokeswoman Shelley Broderick. The father and daughter lived in Falls Church, police said.

Police said Jackson was a former sergeant with the Fairfax County Police Department. They said he left in June 2010 after serving for 16 years.

The shooting occurred between midnight and 1 a.m. Tuesday. Police said a woman called police around 1:15 a.m. to report the shooting.

The brick, single family home where the shootings occurred is in a residential neighborhood, just north of Mason District Park off Columbia Pike.
