Bethany Holguin, 23, of Compton, was pronounced dead at the scene in the 300 block of 131st Street in South L.A.’s Willowbrook neighborhood at 10:33 p.m. Saturday, according to officials. Her brother, 20-year-old Emilio Holguin, suffered major injuries and is in critical condition at Harbor-UCLA Medical Center, their family told KTLA on Monday. The siblings were traveling south on Towne Avenue when a speeding vehicle heading west on 131st Street slammed into their car at the intersection, according to the California Highway Patrol. A surveillance camera captured the violent impact. Investigators believe the driver of the other car was racing with another vehicle, possibly a red Honda. The occupants abandoned their heavily damaged car at the scene and might have fled in the red vehicle, officials said. Witness Fabiola Rodriguez described trying to pull Bethany out of her car after the collision. The victim eventually stopped breathing, Rodriguez said. “I appreciated that she wasn’t alone,” said Rafael Gonzalez, who identified himself as Bethany’s boyfriend. The victim was a single mother to a 6-year-old girl and had been working toward getting a nursing degree, according to her family. Bethany’s friend Edwin Juarez said her daughter was “her everything.” “She loved her daughter,” he told KTLA. “Would always take her everywhere.” Juarez described Bethany as a “loving person” who “didn’t care what people have to say about her.” Several residents said street racing is common in the area. “This is not going to stop until we speak up,” one of them said. Juarez urged the driver involved to come clean. “It’s not right because they left a little girl without a mom, and they just need to turn themselves in,” he said.
