Heartbreaking details have emerged about the father who was critically injured in a school bus crash that killed his son yesterday. Alan Stevens, 68, was driving a 4WD with his son in the passenger seat when it collided with a school bus near Gympie, in Queensland, on Tuesday afternoon. Josiah Stevens, 29, sadly died at the scene before it was uncovered that Mr Stevens reportedly lost another child, Clancy, in a trail bike accident in 2013. The father is still in a critical condition with multiple broken bones, while the twenty-six school children and a female bus driver, 53, involved escaped without any serious injuries.
