Investigators Monday continued to look for a driver who caused an early morning hit-and-run crash in Playa del Rey, killing two people, including a 1-year-old baby.

The crash happened on Vista Del Mar Avenue near Culver Boulevard at around 4:34 a.m. on Sunday, according to the Los Angeles Police Department.

A white Jeep Cherokee traveling southbound on Vista Del Mar Avenue crossed over into incoming traffic on the northbound lane and crashed into a blue BMW, the LAPD said.

The driver inside the white Jeep ditched the car and ran away from the crash site on foot, police said.

The BMW had four people inside, including the 1-year-old. A man, estimated to be around 30 years old, died at the scene. The baby and a 27-year-old woman were taken to a hospital, but the young child ultimately died while being treated at the hospital.

Cory Cooper, who lives in the area, said he tried to help the injured child after he heard the crash.

“When I walked up to the accident, there were some people already there and there was a man holding the child, and it didn’t look like the child was doing well, so we gave him CPR, waited for 911 and then they pulled out another passenger while we were giving CPR and she didn’t look good, either,” Cooper said. “And that’s when the ambulances came.”

Cooper, who is a father of two children, himself, said he called 911 and was given guidance on how to perform CPR on the child until first responders arrived. He said amid his gut-wrenching effort to help, another vehicle arrived at the scene and a woman ran toward them.

“(She) ran over and was holding the child and trying to get him warm, saying, ‘He’s still warm. He’s still warm,’” Cooper recalled. “We held the baby and we tried to give the baby CPR for as long as we could, as best as we could, until the ambulance got there.”

The LAPD reminded the public that a reward of up to $50,000 is available to those who provide information leading to the suspect’s identification, arrest and conviction.

Anyone with information about the collision or the suspect driver was urged to contact the LAPD’s West Traffic Division detectives at 213-473-0234.
