John David LaDue of Waseca, Mn., had it all figured out. He would kill his mother, father and sister and then create a diversion to keep first responders busy while he went to Waseca Junior/Senior High School to wreak havoc, says the Minneapolis Star Tribune. There, the 17-year-old planned to set off pressure-cooker bombs full of nails and metal ball bearings in the cafeteria. Students who weren't maimed or killed would be gunned down in the halls, he told police. After his arrest Tuesday, the high school junior said he intended to kill “as many students as he could,” before he was killed by the SWAT team.
Police Capt. Kris Markeson believes LaDue would have carried out his murderous plot “just because of the amount of preparation and thought he put into this.” LaDue had planned and practiced for 10 months, refining the chemicals in his bombs to try to find a more lethal combination. Police believe the attack would have happened “within the next few weeks” if it hadn't been for an alert 911 caller who grew suspicious after she saw a tall, white male wearing a backpack open a storage unit, go inside and close the door.
