Neighbors say the woman that lives inside the house appeared to be okay. The cause of the accident was not immediately clear. However, the speed is considered a possible one. The bus was carrying students from Woodmore Elementary, who ranged from kindergarten through fifth grade. Some children were escaping from the roof hatch after the crash. However, it took about two hours to get the last children off the bus. Many people donated blood for victims. Tennessee Gov. Bill Haslam called the crash “a tragic event.” “It’s a sad situation anytime there’s a school bus with children involved, which there is in this case. We will do everything we can to assist in what I think is going to be a very sad situation,.” he said. Chattanooga police have arrested the bus driver, 24-year-old Johnthony Walker.
