Delbert Dalton Hobbs was 41 when he disappeared from Anchorage, Alaska. A friend reported their last conversation on the afternoon of August 20, 1966; they had planned a trip for the next morning but Hobbs never showed. Sometime that night he left his trailer and was not seen again.

Investigators found Hobbs’s trailer padlocked from the outside and his vehicles still parked at the residence. There were no visible signs of a struggle and his personal belongings appeared untouched, which left no clear indication he intended to leave for long. Friends and acquaintances were interviewed but provided no leads.

The Alaska State Troopers kept the case open, but the trail went cold and questions remain about whether Hobbs left voluntarily or met with foul play.
