CHATTANOOGA, TN (AP) - Chattanooga police say a sixth child has died from a school bus crash.

A tweet from the police department Wednesday evening said the agency had received confirmation of the death.

Police say the bus was traveling too fast when it veered off a narrow, winding road and crashed into a tree Monday afternoon.

The driver, 24-year-old Johnthony Walker, has been arrested and charged with five counts of vehicular homicide.

The police department's tweet did not give the child's name or age.

Federal investigators say that the site of a school bus crash was not on the designated route.

National Transportation Safety Board Chairman Christopher A. Hart says it's unclear why Walker had taken the bus down Talley Road in Chattanooga. Investigators also don't know whether he had taken the same route before.

Hart says the NTSB is bringing in a specialist to analyze video and audio recordings made on interior cameras that were damaged in Monday's wreck.

Investigators are facing similar challenges in retrieving speed and braking information from the engine control module that has been removed from the bus.
