Patrick Norman Chapman disappeared on May 1, 2020. He was last seen at a family friend's house in Mill Spring, Missouri, and his vehicle, a burgundy 1995 Ford Escort, was found abandoned on a four-wheeler path in a heavily wooded area of the Mark Twain National Forest, less than two miles from where he was last seen. There was severe damage to the vehicle's bumper, all the tires were flat, and the car keys and cellular phone are still missing.

Since his disappearance, his bank account has not been touched and his case remains unsolved.
