Summary based on the NamUs case record (MP36113) and 5 other sources
Keith Allan Kirby, 23, was last seen on October 13, 1990, in Lancaster, California. On the day of his disappearance, he visited a friend's home, but after a short visit, he left and was never heard from again. The following day, his family discovered his vehicle abandoned, raising further concerns about his safety.

Kirby was described as a white male, standing 6'1" tall and weighing about 140 pounds, with blond hair and blue eyes. He was last seen wearing a black shirt with orange sleeves, blue jeans, and tan work boots. He also had several distinctive tattoos, including his initials "KAK" on his right shoulder and a cross on his left shoulder.

Despite efforts to locate him, there have been no significant developments in the case, and Kirby's disappearance remains unresolved. The Los Angeles County Sheriff's Department continues to handle the investigation, hoping that new information will eventually surface to provide answers to his family's long-standing search for closure.
