An arrest has been made in the death of an El Cajon boy. 3-year-old Zachary Foster was visiting his grandparents in Fruitland Park, Fla. when a car drove up on to the front lawn where the boy was playing. Zachary was struck by the vehicle and pushed against a parked car. His father attempted to revive him while waiting for emergency responders, but Zachary later died at a Leesburg hospital. The driver was arrested shortly after the accident on suspicion of leaving the scene of a fatal accident, vehicular homicide, and driving without a license.
