Police in both Maryland and Virginia are investigating why a man drowned in the Potomac River Friday afternoon.
According to Montgomery County Police, witnesses say the man, who appeared to be in his late teens or early 20s, went into the water from the Virginia side -- south of Riverbend Park in Fairfax County -- shortly after noon Friday.
Investigators believed the man, whose identity has not been determined waded to the middle of the river and drowned after somehow becoming trapped under a rock. Montgomery County Fire/Rescue recovered the body in the area of Swains Lock.
Detectives in Fairfax County are attempting to establish the man's identity. It does not appear that foul play was a factor.
Anyone with information is asked to call the Montgomery County Police Homicide/Sex section at (240) 773-5070.
