Investigators trying to identify a man’s body discovered last month floating in the Charles River have turned to the public for help.

Authorities have described the body as that of a pale-skinned white man who was approximately 60 years old, 5-foot-8 and 200 pounds, Suffolk County DA Daniel Conley reported. He was bald except for white hair on the sides of his head and white facial hair.

The body was discovered floating along the Esplanade near the Hatch Memorial Shell on March 10 around 12:30 p.m., Conley stated. The man had a backpack but no personal papers to establish his identity.

He was wearing a dark Carhartt cap, light-colored pants, a blue sweater and a gray Abercrombie & Fitch hoodie with faded yellow lettering, according to the district attorney, who released a photo of the hoodie in an effort to identify the body.

An autopsy did not indicate that the body had sustained any violent trauma, Conley added.
