Roland Himebrook and his 11-year-old grandson Richard Gorham disappeared from Avra Valley, Arizona, after being seen together on the evening of July 7, 1986. Roland, then 53, and Richard lived in Marana; a friend reported them missing on July 12 after not hearing from them. Both left behind all of their clothing and personal belongings, and Roland’s failure to contact his daughter was described as highly uncharacteristic.

On September 27, 1986, Roland’s white 1966 Chevrolet El Camino pickup was found abandoned in the desert near Silver Bell, south of Tucson. Authorities estimated the truck had been there about two months; searches of the vehicle and nearby area produced no sign of Roland or Richard. Investigators noted difficult family dynamics: Richard had been living with his grandfather after running away from his mother’s home, allegedly to escape abuse by her live-in boyfriend, and Roland reportedly had several confrontations with that man, who has been considered a possible suspect.

No public resolution has been reported. Did anyone in the Avra Valley or Marana area have contact with Roland or Richard in July 1986, or recall seeing that El Camino?
