Three teens died and a fourth was injured early Friday morning after the car they were riding in careened off a road near the Anaheim Street bridge over the Los Angeles River in Long Beach.

Fabian Cazares-Garcia, 19, Alicia Yanonis, 17, and Armando Herrera, 19, were pronounced dead at the scene, according to Lt. David Smith of the Los Angeles County Coroner’s Office.

Yanonis lived in Long Beach. Cazares-Garcia’s and Herrera’s places of residence are not known.

A fourth person, only identified as a male, was also hurt in the accident. He was taken to a hospital with moderate injuries, said Brian Fisk, a Long Beach Fire Department spokesman.

“At this point, it appears the vehicle was traveling eastbound on Anaheim, possibly at a high rate of speed, when it left the roadway and landed on the west embankment of the Los Angeles River,” Long Beach police spokeswoman Marlene Arrona said near the scene of the crash.

Anaheim Street’s bridge over the river, as well as nearby onramps and offramps to the 710 Freeway, were reopened to drivers about noon, according to police. The area had been closed to traffic in both directions for roughly six hours after the 4:07 a.m. crash.

“One car with four passengers — three men and one woman — landed on the rocks by the water on its roof,” Long Beach Fire Department spokesman Brian Fisk said early Friday.

Long Beach Fire Department dispatched several units to the scene, including the urban search and rescue team, Fisk said.

“Our units extricated all four victims from the car,” Fisk added.

The cause of the crash was not known. It was under investigation by the Long Beach police and fire departments.
