John Jacob Barnhill, known as Jay, was 62 when he was last seen in Mills, Wyoming, on September 10, 2019. He is described as a White male, 5 feet 11 inches, about 185 pounds, with graying black hair often worn in a ponytail, brown eyes, a gray mustache and possibly a gray beard, and eyeglasses that were reportedly left behind. Distinguishing marks include a white scar on the right side of his torso near the ribs and a large mole on his back near the right shoulder blade.

On the day he disappeared Barnhill told his live-in girlfriend he was going out to run errands and sent several text messages after leaving home but did not return. His girlfriend reported him missing on September 12, 2019. His truck was found on September 14, 2019, well off the roadway near Sheepherder Hill on Casper Mountain in an area of private property and Bureau of Land Management land; the vehicle appeared to have been driven through brush and there was no sign of Barnhill at the scene. Authorities expressed concern about his medical condition, and the Charley Project and NamUs classify him as endangered or missing under MP60982. The case remains unresolved and Barnhill has not been publicly reported as found alive or located deceased.

If anyone saw John Barnhill, his truck near Sheepherder Hill, or has information about his movements after September 10, 2019, please contact the Mills Police Department or the Natrona County Sheriff’s Office.
