Teen gunman kills three children, adult at Oregon elementary school

Three children and one adult were killed in a shooting at Silver Rail Elementary School in Bend, Oregon, on Oct. 15, a law enforcement source told USA TODAY.

The shooter, a 16-year-old who used a shotgun, was killed by a bystander who was legally carrying a concealed weapon and followed the shooter, the law enforcement source said.

Another child and another adult victim were taken to the hospital to receive life-saving measures, and their conditions are touch-and-go, the source said.

USA TODAY has reached out the Bend Police Department. The Deschutes County Sheriff’s Office wouldn't confirm details about the shooter and the number of children shot.

Shelia Miller, communications manager for the Bend Police Department, said at a news conference that "children are among the victims."

She said that the shooter was shot and killed on the scene, possibly by a bystander. Police don't have information on the shooter's identity, she said.

Dispatch received a call at 12:59 p.m. about a shot fired into a car, Miller said. At 1 p.m. dispatch sent out a “tone” that alerted all officers to respond to a critical incident. Officers arrived by 1:02 p.m. The agency received multiple 911 calls within the two-minute span, according to Bend Police.

Oregon Gov. Tina Kotek said in a social media post that she is "closely monitoring the situation" and "grateful to the first responders." FBI Director Kash Patel said in a social media post that the bureau is on the scene and "assisting our local partners in the investigation."

Miller said that Silver River had between 400 and 450 students and about 40 staff members. Bend-La Pine school leaders said that all schools will be closed on Oct. 16 and all extracurricular and athletic events are cancelled.
