Gun-wielding student at Utah school disarmed by his mum

When parents of a teenage boy in Utah noticed that a shotgun, handgun and ammunition were missing from their home, they chased after him fearing the worst. He'd already got to his classroom where he had fired a shot into the ceiling.

One of the students in that classroom at Mueller Park Junior School in Utah - Aliza - explains what happened and how the boy's parents intervened.
