Anungazuk was last seen in Nome, Alaska on September 30, 1982. He has never been heard from again. Anungazuk was subsequently declared dead by a coroner's inquest, but his remains were never found.

Approximately 20 Native Alaskan people have vanished or died under questionable circumstances in the Nome area since the 1960s. Authorites opened a probe into their deaths and disappearances, but they do not believe a serial predator was involved.
