Santa Rosa city workers searching Monday morning for the source of a bad smell found a decomposed body of a man in a downtown storm drain. A complaint about the smell prompted Monday’s search. Public works employees could see the body down below after popping open a manhole cover in the middle of D Street near First Street, on the edge of the City Hall parking lot. They reported the gruesome finding at 11:24 a.m., bringing several police officers and firefighters to investigate and remove the body. The streets were closed to traffic for about two hours. Firefighters positioned a ladder truck near the drain to hoist out the unidentified remains. The noxious smell began to permeate the air as workers prepared for the retrieval. Some area workers and passersby came by to see what was happening, but covered their noses and quickly backed away.
