Homemade Shotgun Backfires on Kid, 13

An Arizona teen underwent surgery on Sunday after accidentally shooting himself with a homemade shotgun he'd assembled with instructions found online. Maricopa County Sheriff's Office says the 13-year-old suffered non-life-threatening injuries when he tried to fire the weapon and was hit in the rib cage by a projectile pipe, reports KPHO and ABC15. Authorities arrived at the scene after getting a call about an adolescent who'd been shot in Buckeye around 4pm, reports NBC News. The teen was taken to Phoenix Children's Hospital; his current condition is unknown. (Read more shotgun stories.)
