Kyles Acosta is a 26-year-old Tohono O’odham man from Sells, Arizona, whose last documented contact with authorities was on December 31, 2024. He is described as approximately 5 feet 8 inches tall, about 185 pounds, with black hair and brown eyes. His primary residence and last known location are on Tohono O’odham Nation land in Pima County.

Acosta’s disappearance was not reported to police until May 26, 2026, when his sister returned to the Nation from Tucson and discovered that other relatives likewise had not seen or heard from him for about two years. The Tohono O’odham Nation Police Department reviewed records and established December 31, 2024, as the final known point in the official timeline, but no exact disappearance date or specific incident explaining his absence is recorded.

The case is entered in NamUs under MP159185 and lists Detective Mike Rivas as the law-enforcement contact. Does anyone in or around Sells remember seeing Kyles after December 31, 2024, or have information that could help locate him?
