Two people critical in hospital as officials in Bend say 16-year-old suspect shot dead by bystander
A 16-year-old shooter opened fire at an elementary school in Bend, Oregon, on Thursday, killing three children and a teacher before he was shot dead by a community member, authorities said at an evening news conference.
The dead children at Silver Rail elementary school were aged five, eight and 11, officials said.
A seven-year-old and a 54-year-old were also hospitalized with critical injuries, according to police.



That assumes he saw a kid with a gun and did nothing while evaluating the situation and getting a 100% confirmation that he is indeed a crazy shooter. Which could really only happen when he saw this kid started shooting other kids. Then he calmly found a location where he would not accidentally hit any bystanders and without missing, terminated the shooter. If that sounds improbable for a real life situation, that’s why OP expressed his doubts.
