Dozens of gunshots were fired Monday near Interstate 215 in Riverside, east of Los Angeles.

CHP Assistant Chief Scott Parker says an officer who pulled over a white pickup was filling out impound paperwork when the driver pulled a rifle from the truck and began shooting.

The officer was fatally wounded but managed to call for help. Authorities say CHP officers, Riverside police and sheriff's deputies arrived and continued trading gunfire. Two other CHP officers were hit before the gunman was killed.

Police withheld the shooter's name and say they don't have a motive for the attack.

Original story below.

RIVERSIDE, Calif. — A shootout near a freeway killed a California Highway Patrol officer and wounded two others Monday before the gunman was fatally shot, authorities said.

A CHP officer had pulled over a white pickup truck at about 5:30 p.m. on a road just off Interstate 215 east of Los Angeles, Riverside police spokesman Ryan Railsback said. He didn't immediately know why the car was stopped.

The CHP decided to impound the truck and a tow had been called when the driver reached into the back of his pickup — apparently to retrieve personal items — but instead grabbed a rifle and opened fire, authorities said.

Three CHP officers were shot. Video showed one officer being taken away in a police car. Another was taken to the hospital by helicopter.

The CHP later tweeted that one officer had died. There was no immediate word on the conditions of the other officers.

Family members identified the officer as 33-year-old Andre Moye, Jr., who was married and had been with the CHP about four years, KABC-TV reported.

Riverside police and Riverside County sheriff's deputies were called and more gunfire erupted as the gunman took cover in front of his car. He was wounded and pronounced dead at a hospital, authorities said.

Someone in another car was hit by flying glass that caused minor injuries, Railsback said.

TV video showed a woman being examined by firefighters.

Video from the scene shows bullet holes in the front windows of two patrol cars and large holes blown in their back windows. What appeared to be an assault-style rifle was on the ground.
