A body found in the Potomac River Friday afternoon belongs to a Caucasian woman, estimated to be 65 to 75 years old, D.C. police said Saturday.

Authorities said they found the body about 1:45 p.m. near a retaining wall, across from the Watergate. The body has yet to be identified, but the woman was wearing a black shirt, blue pants, black sneakers and a pair of glasses along with a gold-colored band on the ring finger of her left hand.

The body was transported to the Office of the Chief Medical Examiner for the District of Columbia for an autopsy. The cause and manner of death have not been announced.
