Joseph Anderson, a 69-year-old Jamestown businessman, was last seen alive on September 12, 1991, at a Ducks Unlimited banquet. On September 16 a foul odor and apparent blood stains on his 1979 Buick Riviera in the Gladstone Inn parking lot led police to the car. Anderson’s decomposing body was found in the trunk, wearing only white Jockey underwear and covered with a green sheet later identified as coming from his home.

An autopsy indicated Anderson likely died within hours of his last meal at the banquet, but the exact cause of death was not publicly disclosed. Investigators reported no signs of a struggle or disturbance at his residence. Anderson had been a prominent local inventor and manufacturer who employed about 100 people and was reportedly exploring business opportunities outside North Dakota.

Authorities said they had some suspects about a year after the killing but lacked enough evidence to charge anyone. No arrests have been announced and the homicide remains unsolved. Did anyone who knew Joseph or saw him at the banquet or around Jamestown in mid-September 1991 see anything that could help this cold case?
