Police say the boy responsible for killing a fellow student at a Troutdale, Oregon high school yesterday was Jared Michael Padgett. 

Police Chief Scott Anderson says Padgett was a freshman at Reynolds High School and confirmed that he died of a self-inflicted gunshot wound.  

Anderson says Padgett used an AR-15-type rifle and was also carrying a semi-automatic handgun.  

Padgett also had nine loaded magazines which were capable of holding several hundred rounds.
