JURUPA VALLEY, Calif. - A man was shot and killed at a Jurupa Valley park-and-ride after he threw a large boulder through the window of a car with a sleeping man inside, officials said.
The man was with a woman around 12:40 a.m. when he approached the car at the park-and-ride along the 60 Freeway and Mission Boulevard, according to the California Highway Patrol.
He threw what was described as a "large boulder" through the car's driver-side window, where a driver was sleeping inside, the driver told investigators.
Officers said the driver, who was armed with a handgun, fired several shots, striking the attacker.
The shooter immediately called 911 to report the incident, CHP Officer Dan Olivas said.
He was transported by ambulance and died at Riverside Community Hospital.
"Once emergency personnel got on scene, the male who was shot was transported to the hospital and succumbed to his injuries," Olivas said.
CHP said the identity of the man is being withheld pending positive identification and notification of next of kin.
Officers report the shooter is not under arrest as he is cooperating with CHP, which is overseeing the investigation as the park-and-ride lot is considered state property.
Investigators said the woman involved in the shooting is being detained and questioned.
The CHP Multi-disciplinary Accident Investigation Team (MAIT) is investigating the incident. Anyone with information is asked to contact the CHP, Inland Division MAIT at (909) 806-2400.
