Ralph William Wesselman Jr., known as Butch, was 21 when he vanished from Yuma, Arizona. He was last heard from on September 24, 1975, during a phone call with family; after that call all communication stopped and he has not been seen or heard from since. He was reported to be in Yuma County at the time.

Descriptions vary slightly: white, long brown hair described as light or dark brown, blue eyes, height between 5 feet 8 inches and 6 feet 1 inch, and weight between 150 and 185 pounds. Distinctive scars on his forehead — two in a V shape and one in a Z shape — were noted. He reportedly wore Levi jeans (a witness called them grubby blue jeans), a brown tank-top style shirt, yellow flip-flops or tennis shoes, and gold wire-frame eyeglasses when he disappeared.

The Yuma County Sheriff’s Office kept the case open as leads dried up, and Ralph’s profile appears on national missing persons databases. Little else is publicly known about his movements or contacts after that September 24 phone call. Does anyone who knew Ralph or saw him in Yuma in late September 1975 have information that could help the investigation?
