Marion County authorities say what was likely a stray shot hit a school bus, but nobody was injured.
The sheriff's department said two children were aboard Wednesday afternoon when the shot cracked the glass about 10 inches above the driver's head. The shot didn't go through.
Deputies said they couldn't be sure, but they suspect it came from a .22-caliber weapon or a pellet gun.
They doubt it was aimed at the bus, which was traveling through an open, flat area.
The bus was from the St. Paul School District.
