Darwyn Hope, a 92-year-old man from Boise, Idaho, was last seen on July 11, 2016, leaving his Collister neighborhood home without his hearing aids and without money. Family members reported him missing soon afterward; he was hearing-impaired and could not communicate effectively without his aids. He had been in significant physical pain and depressed after a much-needed surgery was unexpectedly canceled, and those circumstances led some to wonder whether he might have been despondent when he disappeared.

Hope may have been driving a silver 2003 Pontiac Bonneville that also went missing. He had a history of traveling to McCall, Idaho, and authorities considered that as a possible direction, although his physical condition would have limited how far he could drive. Foul play became a consideration and investigators identified his two sons, Mike and Dale, as persons of interest. Both submitted to polygraph testing; Mike failed and Dale’s results were inconclusive. Police suggested the brothers may have helped their father end his life and concealed a body, a theory the family denies.

Extensive searches and ongoing investigations have not located Darwyn Hope or the Pontiac. Does anyone have information about Hope, his Bonneville, or his movements around July 11, 2016?
