Joseph Awaida, 30, was pronounced dead that evening at a hospital, the DA's office said. His son, 3-year-old Omar, succumbed to his injuries on Nov. 2. The boy's mother, 32-year-old Raihan Faisal Dakhil Awaida, died the following day.
Navarro, who was in custody in connection with an unrelated previous burglary charge, faces a maximum sentence of 45 years to life in state prison if convicted as charged in the fatal crash, prosecutors said.
