The Minnesota teenager accused this week of planning a school massacre didn't just make a few offhand remarks. He laid out his plan in methodical detail in a notebook he kept locked inside his guitar case, and police are convinced that John David LaDue was poised to strike within weeks, reports the Minneapolis Star Tribune. The 17-year-old had a three-stage plan: He would kill his parents and sister at home with a .22-caliber rifle, go to a rural spot to start a fire and draw first-responders, and finally head to Waseco High School to kill as many people as he could with guns and homemade bombs. He planned to be killed himself by police.
“LaDue planned on setting off pipe bombs and throwing Molotov cocktails down the main wing corridors in the school, and then shooting and killing students as they rushed out of the corridors,” says the criminal affidavit, reports NBC News. Police found an assault rifle with 400 rounds of ammo, a 9mm handgun, and at least a half-dozen bombs at the teen's storage unit and home. When officers confronted him in the storage unit, they say he basically taunted them by making them guess what he was doing before answering any questions. When an officer guessed he was making bombs, the teen agreed to go to the station. The plot unraveled thanks to a 21-year-old who called police when she saw LaDue cut through her yard on his way to the storage unit and then act suspiciously outside it. "The flowers I received today—they say, 'Thank you, from a grateful parent,'" Chelsie Schellhas tells NBC.
