Donald George Macvicar, 26, disappeared in Alaska on July 20, 1956, after a boating accident on Chandler Lake near Kotzebue in the Northwest Arctic Borough. Authorities concluded he likely drowned, but his body was never recovered and no definitive cause can be confirmed.

At the time he was reported as a Caucasian male, 5 feet 11 inches tall, about 165 pounds, with brown hair. An uninflated Mae West life vest is the only specific item linked to the incident; why it was not inflated remains an unresolved detail. The official report was not filed with the Alaska State Troopers until December 11, 1996, and the remote location and elapsed time have limited any extensive search or recovery.

Those who knew Donald or have information about boating on Chandler Lake in July 1956 are asked to come forward with anything that might help clarify what happened.
