WASHINGTON — Authorities have retrieved the body of adult male from the Anacostia River near the 11th Street Bridge in Washington.

Officer Araz Alali, a D.C. police department spokesman, says a bystander saw the body about 1:20 p.m. Wednesday and notified authorities. Alali says the body was found near the river’s southeast shoreline.

He says the body had been in the body for a long time, but it was not clear exactly how long.

An autopsy will be performed to determine the cause and manner of death.
