At least one person is dead after a car plunged into the Anacostia River on Sunday morning.

Officer Paul Metcalf, a D.C. police spokesman, said little was known about the crash, which happened between 7:30-8 a.m. He said that investigators did not know what road the car was traveling on before it went into the water near the John Philip Sousa Bridge, nor what caused it to go off the road or the bridge.

At least one adult in the car died, Metcalf said. He did not know whether there were other passengers.
