(CNN) — A sixth child has died from injuries sustained in a school bus crash in Chattanooga, Tennessee, police tweeted Wednesday night. The bus was on its way home from school Monday, Nov. 21, when driver Johnthony Walker swerved off the road and the vehicle, with 37 students on board, plowed into a tree and split apart.

Walker was traveling “well above the posted speed limit of 30 mph” when he lost control of the bus, swerving off the roadway, according to an arrest affidavit. Walker “lost control of the bus and swerved off of the roadway to the right, striking an elevated driveway and mailbox, swerved to the left and began to overturn, striking a telephone pole and a tree,” the affidavit says.

There were no signs of drugs or alcohol in the bus driver’s blood, police investigator Austin Garrett said Wednesday.
