A woman in Everett, Washington, was looking through her grandson's journal Monday night when she found something that would forever change her view of him.

"I'm preparing myself for the school shooting," he wrote, investigators said.
"I can't wait. My aim has gotten much more accurate ... I can't wait to walk into that class and blow all those f****** away."
The next morning, she called police. By that evening, authorities said, her grandson was in jail on attempted murder charges.

Based on his recent journal entries, police believe Joshua O'Connor was planning to shoot students at ACES Alternative High School, which he attended in Everett. And his grandmother is being hailed for potentially sparing the school from a tragedy like the shooting one day later at a high school in Florida.
