Allan Preston Sloan, 29, of Colville, Washington, was last seen December 7, 2021, in the Wapshilla Ridge area south of Waha in Nez Perce County, Idaho. Family reported him missing on December 12 after five days without contact and noted concerns about his mental state and that he may have had a firearm. There has been no activity on his phone since he was last seen.

On the day he disappeared Sloan was arrested by Idaho State Police for speeding and charged with misdemeanor possession of marijuana and psychedelic mushrooms; he was released from Nez Perce County jail the same day. He had been driving a blue 2013 Dodge Ram 2500 pickup with matching aftermarket bumpers, Idaho plate C99346X. That truck was found December 13, 2021, stuck in snow near Craig Mountain with no sign of Sloan.

Law enforcement and the Idaho Department of Fish and Game searched shelters, cabins toward Eagle Creek and the Snake River by boat, but heavy snow and poor weather obscured tracks and hampered dogs, and the official search was called off. Few details are available in the ongoing case. Did anyone in the Wapshilla Ridge or Craig Mountain area see Sloan or his truck around December 7–13, 2021?
