Authorities identified Henry Kingi, a stunt driver for the television show "Dukes of Hazzard," as the victim in the latest episode of Los Angeles-area roadway violence. Kingi, 43, the estranged husband of actress Lindsay Wagner, was driving with his 4-year-old son Saturday evening near the intersection of Ventura and Laurel Canyon boulevards when he and a group of teen-agers in a Jeep got into a fight. In the ensuing fracas, one of the teen-agers shot Kingi, who managed to get in his car and drive to a nearby hospital. Kingi was reported in serious condition with a gunshot wound in the side. Six people were questioned in the case, but none was arrested. The incident involving Kingi was the 22nd traffic-related shooting reported by Southern California law enforcement officials since mid-June.
