WASHINGTON (AP) -- Authorities have recovered a body from the Potomac River after a car traveling on the George Washington Memorial Parkway apparently left the road and plunged into the river.
The operator of a D.C. Duck Tours boat called authorities around noon Sunday saying there was a car submerged in the water near the Humpback Bridge and Interstate 395 and that he could see the silhouette of a person. Divers recovered the body around 1:30 p.m.
Authorities say it appears the vehicle was traveling northbound on the parkway when it went into the Potomac. It was not clear when the car went in the water or what caused it to leave the roadway.
Authorities did not release the name of the person who was found dead.
