Note to Self: Check List Twice

Not one of those "He was so quiet & polite. You'd just never think ..." deals at all.

Students said that even though they were shocked that a shooting occurred, they didn't have trouble guessing who the gunman was.

Senior Rebecca Jackson was in a physics classroom just above where the shooting took place. She told the Bakersfield Californian, "I heard a popping noise and then everything went into lockdown. I knew, like immediately, that it was (the suspect)."

Taft junior Katie Wolfe told the Californian, "He does say stuff like that a lot. I’ve never heard him say a name that he was gonna shoot anybody in specific. I thought he was just kidding ’cause he’d say it all the time, and he never did anything since freshman year."

Angela Hayden, the parent of a student, told the Los Angeles Times the suspected shooter allegedly threatened to kill her daughter and other students last year on a field trip to Universal Studios. She said, "Everybody knew about this kid."

There are lots of unconfirmed rumors circulating on Twitter that Oliver had a hit list and had even been suspended for creating one last year. A few students even tweeted their concerns about Oliver last month.

Authorities confirmed that they are investigating just how long the gunman had planned the shooting, noting that it could have been as long as a year.

“He had intended targets. There's no question,” Kern County Sheriff Donny Youngblood said. "Certainly the two people that he targeted had bullied him, in his mind."

Well, shit, once they've gotten in your mind & are bullying you from the inside, what else can you do?
