A pedestrian was struck by a Fairfax County Fire and Rescue engine early Monday.
Firefighters and police responded about 2:20 a.m. to Glade Drive in Reston for a report of a woman walking in the road, according to WJLA.
As officers arrived, police said the 9-1-1 caller waved crews down, with the fire engine behind them. That's when the woman was hit, and Fairfax County Police Lt. James Curry told reporters at the scene.
"Fire and Rescue personnel immediately exited the apparatus and began life-saving measures," he added.
The victim was transported the hospital where she was pronounced dead.
The investigation is continuing.
