John David LaDue 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.
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, according to charging documents filed in Waseca County District Court.
LaDue was charged Thursday with four counts of attempted first-degree murder, two counts of first-degree damage to property and six counts of possession of a bomb by someone under 18. Police found seven firearms and at least six completed bombs in his bedroom and in the storage unit where he was arrested.
The criminal complaint said LaDue told police that he originally planned the attack for April 20, the anniversary of the Columbine High School massacre that killed 13 people in Littleton, Colo., in 1999.
That was thwarted because that day was Easter Sunday and there was no school.
