The Tennessee bus driver behind the wheel during a wreck that left five children dead was speeding “well above” the posted speed limit on a narrow, winding road, authorities said. Johnthony Walker — charged with five counts of vehicular homicide for the deaths of five Woodmore Elementary School students — lost control of the bus after he drove at “a high rate of speed” on the tiny Chattanooga road, police wrote in an arrest affidavit.

Police have not said exactly how fast Walker was driving, but mentioned that the posted speed limit was just 30 mph.(nydailynews.com)...[+]
