CHP found there was a passenger in the vehicle at the time of the crash. The passenger was pronounced dead at the scene. Officers told the Samaritan about the discovery, who said Domingo had not mentioned there was another person in the vehicle.
Domingo was arrested for gross vehicular manslaughter with intoxicated and has been booked into Vista Detention Facility.
