Donald Lee Walters, 75, of Great Bend, Kansas, was last contacted on July 7, 2020 and reported missing that same day. Walters had been diagnosed with Alzheimer’s disease. A week later, on July 14, his vehicle was located near Tiger Mountain in McIntosh County, Oklahoma. Ground and water searches followed and some personal belongings were recovered near the vehicle, but no further trace of Walters has been found.

Authorities initially issued a Silver Alert because of his medical condition, but the search later shifted to a recovery effort as hope of finding him alive diminished. The case remains open and is being investigated by the Great Bend Police Department and the Okmulgee County Sheriff’s Office.
