A 5-year-old boy cut from a mangled car Sunday and rushed to Harborview Medical Center in Seattle was on life support Monday, KIRO-TV reported.
Earlier, Auburn police said the boy had died.
KIRO-TV spoke with the childs grandfather and reported that the boy was on life support so that his organs could be donated.
The boy was a passenger in a car driven by his mothers 21-year-old boyfriend. The driver and a second passenger, a 9-year-old girl, were also taken to Harborview. He was in the intensive care unit, and the girl was being treated for non-life-threatening injuries, police said.
The three were from Pacific. The mother was not in the car.
Police believe the man was driving at high speed on state Route 164 in Auburn about 2:20 a.m. when he passed a King County sheriffs deputy near the city limits.
The deputy wasnt in his patrol car when the other car sped by and was unable to catch up with the man because he was driving so fast, reports say.
The driver eventually lost control around a bend and hit a tree in the 3600 block of Auburn Way South. Police estimated the car was traveling 90 mph at the time of the crash.
The girl was able to crawl out of the wrecked car. Firefighters cut out the man and the boy.
Police believe alcohol was involved in the crash and are investigating. Vehicular homicide charges are expected to be filed against the driver.
