A mother sustained extensive head injuries after being struck by a hit-and-run driver in South Los Angeles.

Family members told KCBS that Ingrid Argueta, 34, was out celebrating her birthday at 10:45 pm Friday when she was hit. Surveillance cameras filmed the woman walking outside of a crosswalk on 79th Street when a vehicle traveling northbound on Denker Avenue mowed her down.

“I saw she was laying in the street, they were trying to move her and I tried to tell them not to,” a witness told the station. “We were checking [her] pulse, making sure she was breathing. It was getting kind of shallow and then they came on.”

The Los Angeles Police Department (LAPD) said the driver never stopped to help the 34-year-old.

The woman’s cousin, Adam Ayala, told KTLA that Argueta and three other people had been dropped off by an Uber and were en route to a relative’s house when the collision occurred.

“The impact launched her about 10 feet and it was a black SUV. The car did not even hit the brakes it just kept on going,” Ayala said.

“I think they must have been under the influence or something. I mean even if they were scared they should have stopped. It’s pretty cowardly in my opinion to just flee the scene like that. I have no words.”

Authorities said Argueta was treated for cranial bleeding, arm abrasions, a laceration to the back of her head, and possible fractured legs, according to KABC.

Argueta’s family said the mother—if she ever wakes up—will have severe brain damage.

Police said a $50,000 reward is available to anyone who provides information resulting in the driver’s identification, arrest or conviction. Anyone with information pertaining to this case is urged to call Investigator K. Yount at (323) 421-2500 or 1-877-LAPD-24-7.
