The Chattanooga school bus driver in the crash that killed at least 5 children on Monday (Nov 21) has been arrested.

The bus was traveling at a “high rate of speed, well above the posted speed limit of 30 mph,” police said this morning.

Of the five deaths, interim Superintendent Kirk Kelly of the Hamilton County Department of Education told reporters this morning, three of the children were in fourth grade, one was in first grade and the other was a kindergartner, officials said.

Four of the five were girls.

Six students remain in intensive care, but details have not been released.

The bus was carrying 37 children, from kindergartners to fifth-graders, from Woodmore Elementary School in Chattanooga when it crashed into a tree around 3:30 in the afternoon Monday, officials said.

According to an arrest affidavit, the bus was traveling on a “narrow winding road” when Walker lost control.

The bus left the road, “striking an elevated driveway and mailbox, swerved to the left and began to overturn,” then ran into a telephone pole and a tree, according to the document.

Walker is scheduled to appear in court on November 29.

Sending my thoughts and prayers to all of the families impacted by this terrible tragedy.
