A Colorado coroner is asking for the public's help in efforts to identify a man whose body was found in September in the Yampa River, 40 miles west of Craig, Colo.

The unidentified man was discovered Sept. 7, 1990. He had suffered a single shotgun wound to his head. Officials estimate he had been dead for at least two weeks. A sculpture rendition of the body was made, but investigators have had little luck identifying him.The man was described as between 45 and 65 years old, 6 feet tall, 195 to 240 pounds with grey-black hair and blue eyes. He has full upper dentures, partial lowers and has four of his own lower teeth. The appendix is intact and the man has four well-healed scars on the right temple area of the head. He was wearing blue jeans, a four-button knit shirt and tennis shoes with Velcro closures.

Anyone with information is encouraged to contact the Moffat County, Colo., Sheriff's office at (303) 824-4495.
