About six weeks after the body of a man was discovered floating in the Charles River, authorities are now turning to the public for help in identifying him, Suffolk District Attorney Daniel F. Conley’s office said Thursday.

“Investigators have exhausted the traditional methods of identifying the individual, whose body was spotted floating along the Esplanade on March 10,’’ prosecutors said in a statement. “Anyone who may be able to shed light on the man’s identity — or even locations he may have frequented’’ is asked to contact State Police detectives.

According to prosecutors, the man did not have any identification papers when found. Authorities released a photograph of an Abercrombie & Fitch sweatshirt the man was wearing when found. He was also wearing a dark-colored Carhatt stocking cap, light-colored pants, and a blue sweater.
