The man who killed two people and wounded another at a suburban Oregon mall bought more than 100 rounds of ammunition in the days before the December attack.
That information is in a 926-page report the Clackamas County Sheriff’s Office released Wednesday.
The department also released a 7-page PDF with a timeline and other details about the case Wednesday.
Jacob Roberts fired into crowds of people at the Clackamas Town Center outside of Portland before killing himself on Dec. 11.
The 22-year-old stole the rifle he used from a friend that morning. The report says he bought four 30-round magazines for the military-style semi-automatic AR-15 rifle and six boxes of ammunition.
Cindy Yuille and Steven Forsythe were killed, and 15-year-old Kristina Shevchenko was injured. Roberts also fired 13 rounds that did not hit anyone.
He had marijuana and residual levels of cocaine in his system when he died.
