The gunman who opened fire on fellow students at a Washington state high school sent a friend a photo of himself with a gun between his legs minutes before he opened fire, according to a police affidavit, NBC News reported. "Call me before I do this," Marysville school shooter Jaylen Fryberg wrote in the Facebook message, the Everett Daily Herald reported. He also sent ominous messages to a 15-year-old girl, such as: "I set the date. Hopefully you regret not talking to me," "You have no idea what I'm talking about. But you will," and "Bang bang I'm dead.” Fryberg shot five fellow students — killing four of them — before he committed suicide in the Oct. 24 rampage.
