LOS ANGELES (AP) — The driver accused of ramming his car into a crowd outside a Los Angeles nightclub over the weekend was charged with 37 felony counts of attempted murder, prosecutors said Tuesday.

Fernando Ramirez, 29, was also charged with 37 felony counts of assault with a deadly weapon. If convicted, he could face multiple sentences of life imprisonment.

Ramirez is accused of intentionally driving his car onto the sidewalk as partygoers were leaving the Vermont Hollywood venue at the end of a reggae hip-hop event early Saturday. The motive for the attack, which injured 37 people, was still unknown.

A phone number for Ramirez could not be found in an online database search, and the public defender’s office said they have not been appointed to represent him.

“When he drove that car onto that sidewalk, he aimed it at a whole sea of pedestrians,” LA County District Attorney Nathan Hochman said in announcing the charges.

The car came to a stop after colliding with several food carts, which became lodged underneath the vehicle, and bystanders attacked the driver, police said. Injuries ranged from minor to serious fractures and lacerations, and some people were briefly trapped beneath the vehicle.

After fleeing the scene, Ramirez was later found to have been shot in the lower back, but authorities have not identified the suspected gunman. Officials said Tuesday they were still looking for the shooter.

“We understand that this brazen act has shaken the community and but for the good grace of God, this could have been a mass casualty incident” Hochman said.
