The unidentified bicyclist, 12, was struck at a busy intersection Thursday evening and pinned beneath the car. He was taken to Women and Children's Hospital in Buffalo after eight to 10 people lifted the car and freed him.
No charges have been filed against the unidentified driver and there was no involvement of drug, alcohol or cellphone use in the incident, Tonawanda police Lt. Nicholas Bado said.
Gary Stuff, chief of the nearby Ellwood Volunteer Fire Company in Kenmore, N.Y., was shopping in a store at the intersection at the time of the accident, and led the rescue attempts.
As passing motorists stopped to help, Stuff directed them to lift the vehicle off the trapped bicyclist, the Buffalo (N.Y.) News reported Friday.
"I got everybody over on the passenger side of the car," Stuff said. "We lifted the car up to about our waists, and another gentleman slid him out. We did what we had to do to get the kid out from under the car."
An off-duty Town of Tonawanda police detective pulled the boy out from under the car.
The victim was conscious and responsive at the scene, and told the detective his name, age and telephone number, the News said.
An ambulance took the boy to Women & Children's Hospital with life-threatening injuries, where he died Friday.
