Oregon School Shooter Had AR-15 in Guitar Case Police identify Jared Padgett, 15, as gunman By John Johnson, Newser Staff Posted Jun 11, 2014 4:22 PM CDT 211 comments Comments Jared Padgett, identified as the school shooter in Oregon. (Facebook) (Newser) – Police still don't know why 15-year-old Jared Padgett shot and killed a fellow student at Reynolds High School in Oregon yesterday, only that Padgett seemed intent on killing many more people. Padgett brought an AR-15 rifle to school in a guitar case, right on the school bus, reports KOIN-TV. He also had a semiautomatic handgun, though he didn't use it, along with a large knife, a camouflage helmet, an ammo vest, and nine loaded magazines with several hundred rounds, reports the Oregonian. Authorities say he brought the weapons from home, after foiling a security system that secured them. Padgett encountered his victim, 14-year-old Emilio Hoffman, in a locker room and fatally shot him. Police say they don't know of any connection between the two boys, reports CNN. A teacher grazed by a bullet, Todd Rispler, managed to sound the alarm, and Padgett killed himself inside a bathroom as security officers closed in, say police. “I cannot emphasize enough the role Mr. Rispler played,” says the police chief in Troutdale.
