At least 2 students killed, several injured in school bus crash in Tennessee: 'A parent's worst nightmare'

At least two students were killed and at least seven other people were injured Friday after a school bus was involved in a multi-vehicle crash Friday in West Tennessee.

Tennessee Highway Patrol Maj. Travis Plotzer said during a news conference Friday that the crash took place on Highway 70 in Carroll County, and involved a state Department of Transportation dump truck, a Chevrolet Trailblazer and the school bus.

Plotzer called the incident "a parent’s worst nightmare."

Officials are investigating the cause of the crash but said it appeared that the transportation department dump truck did not contribute to the incident.
