Fifteen other children sustained injuries such as bumps, bruises and cuts, police said, and were treated at nearby hospitals.
Tezsla's neighbors declined to comment on Thursday. There were signs of the children around the one-story home: a basketball and a volleyball on the grass, a sled leaning up against the front of the house with two ice skates hanging from it.
The State Police tweeted condolences: "NJSP hearts go out to the Tezsla family for the loss of their daughter & prayers for the recovery of the injured children."
John Kelly, whose 11-year-old daughter attends Chesterfield Elementary, said the Tezsla girls were in his house recently and played with his daughter, the Associated Press reported.
"It's devastating. My wife can't come out or anything," said Kelly, who was picking up his daughter, who walks to school.
Township Police Chief Kyle Wilson said the dump truck, belonging to Herman's Trucking of Wrightstown, was traveling along Bordentown-Chesterfield Road (County Route 528) and the bus along Old York Road when the truck struck the bus on the driver's side at the intersection at 8:05 a.m.
The impact, toward the rear of the bus, sent the vehicle into a light pole.
About 25 children were on the bus, Wilson said. He said he could not say where Isabelle was sitting.
EMS units were on the scene in less than two minutes, Wilson said, and a house at the intersection was used as a triage station.
A boy being taken from the scene told the AP that "this big truck just came and slammed right into us." The boy said some students left the crash with bloody faces. His mother did not want the boy's name used.
