Officers met with the grandmother at her Everett home, where she showed them excerpts from her grandson’s journal. They found a rifle stored in a guitar case. The journal contained statements and detailed plans to shoot students and use homemade explosive devices at the school. “I’ve been thinking a lot … I can make this shooting/bombing at Kamiak infamous. I need to get the biggest fatality number I possibly can. I need to make this count. I’ve been reviewing many mass shootings/bombings (and attempted bombings). I’m learning from past shooters/bombers’ mistakes, so I don’t make the same ones,” the suspect wrote in hid journal.
The grandmother told officers that her grandson had recently purchased inert grenades, which he discussed making “live” in his journal by filling them with black powder, according to police documents. He also wrote about making pressure cooker bombs and where and in what order he would be placing his explosives, documents said. When arrested at ACES High School, he was carrying a knife and marijuana. Being at the Everett Police Department South Precinct, he managed to get one of his hands out of the handcuffs and then ran across the parking lot before captured again.
