REDONDO BEACH, Calif. >> Authorities say a 6-year-old boy whose mother was killed when a motorist slammed into a crowd outside a California church has also died from his injuries.

Los Angeles County coroner’s Lt. David Smith says Samuel Gaza died late Thursday at a hospital.

Five children and eight adults, including the suspect and the other driver, suffered injuries including broken bones, abrasions and head trauma in the crash Wednesday night.

Three adults later died, including the boy’s mother, 36-year-old Martha Gaza of Torrance.

Margo Bronstein was arrested on suspicion of driving under the influence and vehicular manslaughter and was expected to make her first court appearance either Friday or Monday.
