Jacob Tyler Roberts had armed himself with an AR-15 semiautomatic rifle and had several fully loaded magazines when he arrived at a Portland mall on Tuesday, said Clackamas County Sheriff Craig Roberts.
The sheriff said the rifle jammed during the 22-year-old’s attack, but he managed to get it working again. He later shot himself. The sheriff said authorities don’t yet have a motive.
A law enforcement official has told The Associated Press the shooter did not have a criminal record. The official spoke on condition of anonymity because he was not authorized to discuss details of an ongoing criminal investigation.
Two people – a 54-year-old woman and a 45-year-old man – were killed, and another, Kristina Shevchenko, whose age could not be confirmed, was wounded and in serious condition on Wednesday.
