Summary based on the NamUs case record (MP18155) and 7 other sources
Charles Detweilder Allen, a 24-year-old man, was last seen on October 21, 1985, in Arcata, California. At the time of his disappearance, he was reported to be in a distressed mental state and may have been carrying a handgun. Allen stood 5'10", weighed around 140 pounds, and had black hair and brown eyes. A longtime friend reported him missing on November 4, 1985, after he had not been heard from for several days.

Allen's case remains unsolved, and few details have emerged about his disappearance over the years. Authorities have not confirmed any foul play, but the circumstances around his mental state and the possibility of him being armed have raised concerns. Despite ongoing efforts, his whereabouts remain unknown.

The Arcata Police Department is handling the investigation, and anyone with information is encouraged to come forward.
