Authorities have made a positive identification of a 23-year-old Compton mother killed in aWillowbrook-area crash that police say was caused by a street racer.

Bethany Holguin was pronounced dead at the scene of the crash, which occurred at 11:24 p.m. May 11 at 131st Street and Towne Avenue, according to the California Highway Patrol. Her brother was hospitalized in critical condition.

CHP officials said Holguin was driving a 2005 Toyota Camry south on Towne Avenue when her car was broadsided by a speeding Infiniti racing west on 131st Street.

“The Infiniti was traveling at a high rate of speed while actively engaged in a street race with a red sedan,” according to the CHP.

The Infiniti’s driver ran through a stop sign and slammed into the Toyota, causing the Toyota to strike a parked Harley-Davidson motorcycle and a parked Ford Mustang, officials said. The driver and passenger in the Infiniti survived the crash, jumping out of the vehicle and got into a red sedan, fleeing the scene. The Infiniti driver was described only as a man in his 30s.

Holguin’s passenger—identified by relatives as her 20-year-old brother, Emilio—was taken to Harbor UCLA Medical Center with “major injuries.”

Family members told reporters Holguin had a 6-year-old daughter. Holguin was on her way to pick up her daughter and then travel to Hemet to celebrate Mother’s Day with her mom, relatives said.

Neighbors described hearing the crash and said they saw the gravely injured young woman in the crumpled wreckage.
