Rupert Leo Brown, a 42-year-old Native American man, was last seen on December 31, 2020, in the Beaver Creek Housing area near Riverton, Wyoming. Around 1:00 p.m. he left his residence on foot to visit someone at another apartment but never arrived. He was last seen wearing a white sweatshirt, jeans, and black-and-white running shoes and has a scar on his left cheek and another near his right eye.

There has been speculation he may have traveled to the Northern Cheyenne Indian Reservation in Montana, where he has connections, but no confirmed sightings or evidence have surfaced. Local authorities are investigating, and family-led search parties and public appeals have been part of ongoing efforts; few new details have emerged since his last known contact.

Did anyone in the Riverton or Northern Cheyenne communities see Rupert around December 31, 2020, or have information about where he might have gone?
