Oregon shooter reported being assaulted and bullied before attack

Police reports obtained by NBC News show that the 16-year-old shooter in Bend, Oregon, who killed three children and a teacher at Silver Rail Elementary School, had been assaulted and bullied in recent years.

According to the reports, the shooter told police he was punched by a man who had been seeing his mother and hit by a friend of his sister. One incident involved the shooter defending his mother and another involved being slapped and punched by his sister’s friend, which caused a chipped tooth.

Police noted that the shooter likely had a cognitive disability and had reported being bullied at school to his sister. Court and police records also indicated a tumultuous home life with both parents involved in violent encounters and financial instability.

The shooter opened fire on a special-needs classroom before being stopped by a man with two daughters at the school. Law enforcement continues to investigate the shooter and any potential motives behind the attack.
