A stray bullet hit a rental car stopped at a red light in SeaTac on July 4.

The bullet nearly missing a couple and their young daughter who had rented the car at Sea-Tac Airport to visit relatives in Tacoma.

Sgt. Cindi West with the King County sheriff's office said it's almost impossible to find the gun because the stray bullet could have traveled more than a mile from where it was fired.

She noted Fourth of July celebratory gun fire is pretty common.

The busy intersection where the shooting happened is just outside the airport.
