David Edward Johnston was 30 when he was last seen in Brainerd, Minnesota, on April 8, 1988. He is described as a white male, 5 feet 10 inches, about 165 pounds, with brown hair and brown eyes, and scars on his neck and abdomen.

David reportedly left all his personal belongings behind and did not leave a note or other communication. The Crow Wing County Sheriff’s Office opened the investigation after he was reported missing; the Minnesota Bureau of Criminal Apprehension continues to list him as missing. Over the decades the case produced few clues, no clear evidence of foul play, and no indication that he left voluntarily, leaving the circumstances of his disappearance unresolved.

Does anyone who knew David or was in Brainerd in April 1988 have information that could help fill the gaps in his timeline?
