Donald Edward Pauling, 31, of Minneapolis vanished after a single day in April 1965. He resigned from his job on April 15, 1965, and had no further contact with family or friends after that resignation. Pauling is described as 6 feet 1 inch, 230 pounds, with blonde hair and blue eyes.

There were no confirmed sightings after he left work and no clear leads about where he went. DNA is available for identification, but investigators have not uncovered further clues about his fate. The disappearance remains unresolved and the case is still open.

If anyone knew Donald, worked with him, or remembers seeing him around April 15, 1965, please contact the authorities with any information.
