LOS ANGELES A stunt driver for the television series "Dukes of Hazzard" was shot and wounded at a North Hollywood traffic light, becoming the latest victim of roadway violence gripping Southern California.

The Saturday night attack on Henry Kingi, 43, estranged husband of actress Lindsay Wagner, followed two other shootings the same day that left two people wounded, and brought to 22 the number of traffic-related shootings reported in and around Los Angeles since June 18.

In all, three people have died and seven have been wounded in freeway gunplay.

Six people were injured in a four-car pileup Saturday triggered by an angry driver south of Los Angeles.

Kingi, a stunt driver for many of the car crash scenes in the old CBS adventure-comedy TV series, was reported in serious condition with a bullet wound in the side.

He was driving with his son, Dorian, 4, on Laurel Canyon Boulevard at about 7:15 p.m. when the driver of a jeep cut in front of him, said police Lt. Ron La Rue.

Kingi told police the jeep with six occupants, two men and four women, pulled up next to him at a traffic light and the occupants began shouting profanities. Both Kingi and the people in the jeep left their vehicles, La Rue said.

One of the people in the jeep shot Kingi.

The occupants of the jeep were stopped by police about 40 minutes later, but the suspected gunman, identified as Thomas Robison, 18, was gone, La Rue said.

Two people were hit by shotgun fire Saturday afternoon in the coastal community of Venice in a traffic quarrel.

Police arrested the suspected gunman, Gustavo Perez, on suspicion of attempted murder. The two victims were treated at a hospital.

Richard Buttles, 31, of Rubidoux, Calif., and Richard McCauley, 29, of Bloomington, Calif., were arrested Saturday in the Riverside County community of Moreno Valley, about 75 miles east of Los Angeles, on suspicion of firing a handgun at a tractor-trailer.

No injuries were reported, but two teenage witnesses told police they saw the suspects laugh as one fired a gun at the rig. It was not clear how many shots were fired, if any hit the truck or whether a traffic confrontation preceded the episode.

Motorists on Southern California's highways are driving defensively and readily alert police about reckless drivers, authorities said.

California Highway Patrol Officer Diane Lowery said people have started pointing out crazed drivers who create potentially violent situations.

"There's always a set of people who don't call and report anything, and it seems that more of those people are now coming forward and reporting things," Lowery said.
