Robert Alkire, 58 and a member of the Standing Rock Sioux Tribe, was last seen October 1, 2025, in Lander, Wyoming. He had been living at a residence on the Wind River reservation but went missing away from that specific tribal location. He is described as an American Indian male with gray or partially gray hair, brown eyes, 5 feet 9 inches tall and about 180 pounds.

The disappearance was not reported to the Bureau of Indian Affairs until June 24, 2026, and the BIA Wind River Agency opened an official case on July 1, 2026 (agency case I-26-0000000445).

The investigation is being handled by the BIA Wind River Agency. Anyone who knew Robert, saw him around Lander or Wind River in early October 2025, or has information about his movements after that date is urged to come forward.
