Kirby Lee Abeita was 43 when he left his home in Santo Domingo Pueblo (Kewa Pueblo), New Mexico, on October 10, 1999, and never returned. He was described as American Indian/Alaska Native, five feet six inches tall, about 145 pounds, with graying black hair and black eyes. At the time he was last seen he reportedly wore a camouflage jacket and a black or blue beanie hat.

The Bureau of Indian Affairs Office of Justice Services in Albuquerque handled the investigation, but public details about searches or leads are sparse. No note or obvious sign explained his departure, and his disappearance remains unresolved decades later.

If anyone in Santo Domingo Pueblo or the surrounding area remembers Kirby, his habits, where he went that day, or any detail that could help, please come forward with information.
