A 17-year-old high school junior from Oregon planned a Columbine-style attack on his high school, manufacturing six different bombs and hiding them in a secret compartment in his bedroom.
Grant Acord will be charged as an adult, said Benton County District Attorney John Haroldson.
He said Acord had written plans, a checklist and a specific timeline for the attack. The bombs that investigators found included pipe bombs, Molotov cocktails, a Drano bomb and a napalm bomb, Haroldson said.
"That said there were also some indications that it could happen at any time, too," Haroldson noted. "So you have - A -the methodical planning and then - B - I suppose he could get really excited about it and go early.
"In any case that you have a young person that in essence plans to take a video game approach to killing people at school, you have to take a close look at the mental health issues," he added. "And the process will certainly provide for that once he's represented by counsel."
"I can't say enough about how lucky we are that there was an intervention," the district attorney concluded. "When I look at the evidence in the case, I shudder to think of what could have happened here."
