Mother in Bremerton school shooting makes deal - NBC Right Now/KNDO/KNDU Tri-Cities, Yakima, WA |

PORT ORCHARD, Wash.--  Jamie Chaffin pleaded guilty to two charges of unlawful possession of a firearm, with each count bringing a potential sentence of 14 months in jail.

Deputies say Chaffin caused the shooting through the negligence of leaving the handgun where the boy could pick it up at their house.

The gun accidentally went off when the boy set down his backpack. The bullet struck a girl, nearly killing her. 

Prosecutors blame the boy's mother and the woman's boyfriend for the shooting because they left the handgun where the boy could pick it up.
