Ronald Chris Peterson, known as Ron, was last seen leaving his Phoenix home at about 1:00 p.m. on July 23, 1994. He lived near North 89th Avenue and West Thomas Road. At the time he disappeared he was 44, described as a white male with blond or strawberry-blond hair, blue eyes, a mustache, 5 feet 6 inches to 5 feet 10 inches tall, 190–200 pounds, and with a scar on his abdomen below his navel.

When last seen he was wearing a large blue shirt, blue jeans (34-inch waist, 29–30 inch length) and size 11 white sneakers. Two days after he vanished his white 1986 Toyota Camry (Arizona plate DLS774) was found abandoned and unoccupied in desert terrain south of 91st Avenue and West Baseline Road. The Phoenix Police Department opened an investigation two days after his disappearance and the case has been classified as an endangered missing person.

Very few leads have emerged and the family continues to seek answers. If anyone knew Ronald, saw that Camry in the days after July 23, 1994, or has information about his movements that afternoon, please come forward.
