Charles Paxton Anderson was 33 when he disappeared from Chico, California, on May 22, 1981, or possibly the early morning of May 23. He left his residence after borrowing a friend’s Ford truck; that vehicle was later found with blood stains and damage from a shotgun blast in the cab.

Despite extensive investigations, Anderson has never been located and his remains have not been found. The case remains open and cold, and investigators and his family say the circumstances strongly suggest he suffered violent harm, though no resolution has been announced.

Does anyone who lived in Chico in 1981 remember Charles, the Ford truck, or any unusual activity around May 22–23 that could help investigators?
