TWO children, seriously hurt in the Singleton school bus crash that killed nine-year-old Harry Dunn, remained in a stable condition in hospital yesterday.
A Hunter New England Health spokesman said it was unknown when the injured boys - Harry's brother, Luke, and Jacob Simpson, both 7 - would be discharged.
Harry, a St Catherine's Catholic College student, died as a result of a collision between a Hunter Valley Buses bus and a prime-mover at the intersection of Church and Kelso streets about 3.50pm on Monday.
He was pronounced dead at the scene.
Tributes for Harry and his family continued to flow yesterday, with flowers, teddy bears and notes left at the scene of the accident.
Newcastle Crash Investigation Unit commander Sergeant Peter Stace said officers were focusing on whether the truck failed to stop at the intersection in the moments before the accident.
He said police had examined both vehicles on Monday night and found nothing mechanically wrong with either.
Investigators were waiting on the results of blood and urine tests from the McCarthy Transport truck driver, 34, and the bus driver, 54.
Sergeant Stace said police did not believe speed or fatigue were factors in the crash.
It is believed the truck driver, who was discharged from Singleton hospital on Monday night, has spoken to police.
No charges have been laid.
Mr Taylor, who suffered head injuries when the truck collided with the driver's side of the school bus, has also been discharged from hospital. A Hunter Valley Buses spokesman said the company was "co-operating closely with police as they investigate the cause of this terrible accident".
Officers attached to the Newcastle Crash Investigation Unit, with assistance from Hunter Valley police, are investigating the circumstances and want to speak to anyone who saw the crash.
