(Associated Press) A school bus driver had no drugs or alcohol in his system when he careened off a road and smashed into a tree, killing six elementary schoolchildren, police said Wednesday.
Chattanooga Police Sgt. Austin Garrett said a toxicology test was performed on Johnthony Walker, 24, the bus driver now in jail on five vehicular homicide charges.
Later Wednesday, the police department said in a statement that a sixth child had died of injuries from the crash and another vehicular homicide charge would be added.
Federal authorities said Walker left the designated bus route and had driven onto a curvy road while carrying 37 children on their way home from Woodmore Elementary School.
Police said he was driving well over the posted 30 mph limit when he lost control of the bus and slammed into a tree. Five children remain in the hospital.
