PORTLAND, Ore. (AP) - Police say the gunman who killed two people and himself in a shooting rampage at an Oregon mall was 22 years old and used a stolen rifle from someone he knew.
Clackamas County Sheriff Craig Roberts says that Jacob Tyler Roberts had armed himself with an AR-15 semiautomatic rifle and had several fully loaded magazines.
