COATS, Judge. On October 19, 1978, George Schroff, a probationer, learned his probation officer intended to revoke his probation. Schroff, who was living with his mother and stepfather, decided to leave the Anchorage area for California. Upon leaving his house Schroff picked up a .22 caliber automatic handgun to take with him. Schroff spent the day hiding from the police and inhaling aerosol which Schroff said he did to escape from everyday troubles. Toward evening Schroff got on a bus driven by Shelly Clark, who recognized Schroff as looking like someone the police were searching for, described in a police bulletin. Schroff told Clark he was in trouble and the police were searching for him. He also told Clark he was planning on leaving the state. Clark stopped the bus at a service station, telling Schroff she had brake trouble. Clark called her office and had them call the police to inform them Schroff was on the bus. She then got back into the bus and continued to drive the bus with Schroff as the only passenger. A police car driven by officer Bohannon soon pulled in front of her, blocking the bus. Clark left the bus and told Officer Bohannon that Schroff was on the bus. At this point Schroff got into the driver's seat of the bus and drove off with it. Schroff drove the bus through a residential area with Officer Bohannon in pursuit. Bonhannon was soon joined by other police cars as the bus zigzagged through the residential area. The bus finally went out of control and ran into a parked car.
