CARUTHERSVILLE, Mo. (AP) — Authorities in far southeastern Missouri are investigating whether a stray bullet wounded an 11-year-old girl who was shot in the neck while traveling with her family on Interstate 55.

The girl from Kirksville was treated at a hospital after the shooting Saturday evening and was released Sunday morning.

Pemiscot County Sheriff Tommy Greenwell says the vacationing family was southbound when they say the driver’s side window suddenly blew out.

Greenwell says deputies have been contacted by a person who was shooting his pistol about the time the girl was shot, perhaps making the bullet a stray one and the shooting accidental.

The family resumed its trip after the girl was released from the hospital.

There was no immediate word about any arrests.
