essed his weapon, Williams said. A law enforcement official briefed on the shooting last week told The Associated Press the shooter's gun was bought by his mother. The official spoke to The Associated Press on the condition of anonymity because they were not authorized to publicly discuss the investigation. We don't know if the shooter's mother qualified to own a firearm. We don't know whether or not the dealer was aware that the firearm was being bought for a minor, Williams said, adding that there are various issues there we're trying to suss out. Under Oregon law, a minor may possess a shotgun if provided by a parent or by someone else with the parent's consent. The attacker's mother, Shauntai Nickerson, has not responded to messages from The Associated Press. Nickerson on Friday told some reporters outside her apartment near the school that if she could have done something to prevent the shooting, she would have. Police said John got into the school by shooting through locked doors. Authorities said he was not currently enrolled in the Bend-La Pine district but had once been a special needs student at the school. Williams said they are trying to determine whether the school district is liable or not, and if it is, work with the school district to come to some sort of conclusion, you know, and resolution, ideally safeguarding this from happening again in the future. Classes and activities were suspended Monday and Tuesday across the district. No reopening plan has been announced for Silver Rail.
