The body of an unidentified man was found Thursday in a marshy area near the Little Calumet River in northwest Indiana, and police are asking the public for help in identifying him.

About 3:45 p.m., officers were sent to investigate a report of a body in a marsh near 35th and Chase streets in Gary, Indiana, according to Gary police Lt. Dawn Westerfield.  A male body was recovered and pronounced dead at the scene by the Lake County coroner’s office.

The person, who has not been identified, was described as a 5-foot-8, 200-pound black male with short black hair, according to the coroner’s office. He had a mustache and facial hair on his chin. His age was not immediately known.

He was wearing black Five Star boots in size 11W, with long black socks; a red, men’s tall XL Eddie Bauer jacket; a gray 2XL hooded sweatshirt with a picture of a bird on the front and back, and a “Dr. Denim” logo on the left side; a black long-sleeve USA Classic sweatshirt with the words “Red Deer Trail” on the front with a picture of two bucks and a tree, and the words “Tough Wear” in green on the bottom; a black long-sleeve T-shirt, and camouflage briefs, the coroner’s office said.

Police were conducting a death investigation. The coroner’s office said he did not have any apparent injuries, but his manner of death has not yet been determined.
