Cornelson has been hunting since she was a girl and says she remained calm as a customer pulled up to the other side of her kiosk in Coeur d'Alene, distracting the teen.
Cornelson quickly whipped out her 9 mm Kel-Tec pistol, which was a Christmas present from her husband. That scared off the teen so Cornelson could call police.
A sheriff's deputy was nearby after picking up a beverage at the stand and caught the suspect. The teen was later taken to a juvenile detention center.
