District Attorney John Champion tells WMC-TV in Memphis, Tenn., that a 10-year-old student was transported by helicopter Monday to Le Bonheur Children's Medical Center in Memphis.
Champion says authorities have received word from the hospital that the boy is going to be OK.
The bullet went through a side window of the South Panola bus, carrying about 15 students when the incident occurred.
Champion says investigators believe the shooting could have been a hunter.
Champion says so far a person has been cooperative in their investigation as they see what he was doing out there and why the shot was fired.
