Chattanooga police are looking into whether 24-year-old Johnthony Walker was speeding before the crash occurred.
He is also charged with reckless endangerment and reckless driving. His bond has been set at $107,500.A child who was on the bus described how he was driving prior to the crash.

An affidavit filed in Hamilton County court states that Walker was traveling at a high rate of speed, well above the posted speed limit of 30 miles per hour at the time of the crash.
Investigators said he lost control of the bus and swerved off the roadway to the right, striking an elevated driveway and mailbox.
He swerved to the left and began to overturn, striking a telephone pole and tree, according to the affidavit.
A team of investigators from the National Transportation Safety Board will arrive in Chattanooga Tuesday.
The five children killed in the crash were in kindergarten, first and fourth grade.
Walker worked for Durham School Services and was contracted out to the school system.
