TROUTDALE, Ore. -- A clearer picture is beginning to emerge of the horrible events that played out at Reynolds High School, and in the above video KATU's Joe Douglass walks you through step by step what happened that tragic morning.
Police say Tuesday morning 15-year-old Jared Padgett got off a school bus and walked into a building on campus that houses the school's two gymnasiums. He made his way into the boys' locker room where he suited up for the attack.
Officers say Padgett took two guns and nine loaded magazines out of a duffel bag and guitar case that he was carrying.
"The shooter used an AR-15 type rifle in the attack and carried, but did not use, a semi-automatic handgun," said Troutdale Police Chief Scott Anderson.
Officers say 14-year-old Emilio Hoffman walked into the locker room and Padgett fatally shot him.
"We have not established any link between the shooter and the victim," said Anderson.
Police believe Hoffman may have just been at the wrong place at the wrong time.
Physical education teacher Todd Rispler heard the shooting and saw Padgett in the locker room.
“Mr Rispler was shot once, suffering a grazing wound to his hip," said Anderson.
Rispler ran wounded to the main building where he was able to tell administrators to lock the school down immediately.
Police were dispatched at 8:07 a.m. The school's two resource officers were among the first to respond.
"When units arrived on scene,” said Sgt. Carey Kaer, spokesman for the Troutdale Police Department, “they got a team together and they entered."
Police followed Padgett as he ran into a men's room in the lobby of the gym building.
“We know there was an exchange of gunfire between one of the first responding officers and the shooter," Anderson said.
Officers dropped back and sent in a robot with a camera that found Padgett slumped on a toilet. Police say he died from a self-inflicted gunshot wound.
Police say if it wasn't for the quick action of Todd Rispler, Padgett could have easily made his way to the main school building and this horrible attack could have been even worse.
