A Pacific boy who died from injuries suffered in a Sunday car crash in Auburn was 5-year-old Stacey Holmes, the King County Medical Examiner's Office said Thursday.
The boy died at the hospital Tuesday from blunt force injuries to his head, neck and torso, the office said.
Stacey and a 9-year-old girl were riding in a car driven by his mother's 21-year-old boyfriend, when the man lost control and hit a tree about 2:30 a.m. in the 3600 block of Auburn Way South, police said.
All three, from Pacific, were taken to Harborview Medical Center. The Seattle Times reported the driver was in critical condition Thursday. The girl was treated for injuries that were not life-threatening. The mother was not in the vehicle.
Police believe the car was going up to 90 mph at the time of the crash.
Investigators also think alcohol was involved in the wreck, and expect vehicular homicide charges to be filed against the driver, Auburn police said.
