The teenager who committed suicide with a sawed-off shotgun inside his western New York school last week left behind a journal in which he wrote about wanting to kill "just to kill."

Police in Canandaigua released excerpts from 17-year-old Thomas Kane's journal, including an entry made May 5. That's the day he shot himself in a bathroom at Canandaigua Academy, a public school 25 miles southeast of Rochester.

Kane wrote that he wasn't bullied and tormented, but had a growing hatred "towards all the people in that school." The teen also wrote, "I'm not just another school shooter."

Police say Kane had 30 rounds of ammunition on him and in his locker. Two Molotov cocktails were also found in his locker.

No one else was hurt.
