The driver accused of ramming his car into a crowd outside a Los Angeles nightclub over the weekend was charged with 37 counts of attempted murder, prosecutors said on Tuesday. Fernando Ramirez, 29, was also charged with 37 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.
