- Flags will fly at half-staff on Tuesday in the state Capitol in honor of the California Highway Patrol officer who killed on a Riverside freeway.

Moye was killed about 5:30 p.m. Monday, after he pulled over the shooter in a white GMC pickup for an unknown reason off the 215 freeway and chose to impound his truck.

Authorities say a CHP officer was doing paperwork to impound the pickup truck when the driver reached in, grabbed a rifle and fatally wounded the officer, identified as 33-year-old Andre Moye, Jr.

Riverside authorities say a CHP officer stopped the suspect driving a GMC pickup truck and then made a decision to impound the vehicle. Moye was able to radio for help and other officers engaged in a "long and horrific gun battle", Riverside Police Chief Sergio Diaz said.

The first officer was flown by a helicopter ambulance to a local hospital, where he died, Parker said.

Dozens saluted as the officer's flag-draped body was removed from a hospital and placed in a hearse.

The shootout occurred around 5:30 p.m. (0030 GMT) in Riverside, California, about 55 miles (86 km) east of Los Angeles just off U.S. Interstate 215, CHP Assistant Chief Scott Parker said at a press conference.

Moye graduated from the CHP Academy in March 2017 and was assigned to the Riverside area.

He is survived by his wife, mother, father, stepfather, two brothers, two sisters and a large extended family, Dance said.

"Tonight, I mourn the loss of one of our own", CHP Commissioner Warren Stanley said in a tweet.

"I am devastated by the tragedy that unfolded earlier in Riverside".

"One of our officers succumbed to the injuries sustained", a CHP representative said on Twitter late Monday. Family members said he previously worked as an electrician but had dreamed of being an officer since he was a child.

His motive for shooting the officer is still unknown.

Parker said two civilians received superficial injuries and "they're going to be OK".

Giving an update on the investigation, Diaz told reporters: "Here's what we don't know at this time: we don't know where the suspect was coming from, where he was headed to, what his affiliations are".

The suspect shot the officer with a rifle. The gunman, whose identity has not been released, was also killed, Victor Valley News reported.

KABC-TV reported that a man identified the shooter as his son, Aaron Luther, 49, of neighbouring Beaumont.

"I don't believe that, knowing him as well as I know him", he said. "And I'm sorry for the policeman", he told the station.

Two CHP officers who responded to the call for backup were shot and wounded during a gunbattle with the suspect, including one who hospitalized in critical condition.

"I'm devastated", he said.

Jeffrey Callison, a spokesman for the California Department of Corrections and Rehabilitation, says Tuesday Aaron Luther began his prison sentence in 1994 and was paroled in April 2004.
