Richard Allen Houghland disappeared with his brother, Thomas, and their mother, Norma, from Sacramento, California on July 15, 1978. They didn't have air conditioning at home and during hot weather Norma would often take the children for rides in the car to stay cool. They may have done that on they day they disappeared. The only thing that was missing was Norma's car, a gold or light blue 1965 Pontiac LeMans with the California license plate number 254SBI and the vehicle identification number (VIN) 237375K134785. It has never been found.
