Authorities are looking into whether another vehicle might be to blame for the Morehouse College bus crash that happened near Atlanta Saturday morning.
Witnesses told police they saw a car cut the bus off right before the accident.
They say the bus then skidded on the rain-wet pavement and off the road.
The bus was carrying 42 members of the Morehouse College marching band and others to a football game in Albany, Georgia.
Thirteen students were taken to hospitals with non-life-threatening injuries. All but one have been released.
