A 17-year-old boy is facing attempted murder charges after being arrested this week in connection with homemade bombs found on the playground of a Waseca elementary school in March. John David LaDue of Waseca was charged in juvenile court Thursday with four counts of attempted first-degree murder, six counts of possessing explosive devices and two counts of first-degree criminal damage to property. He was arrested after a search of his home and a storage facility turned up multiple firearms and explosive devices. Authorities say that LaDue had planned to shoot and kill his mother, father, and sister in their home, and then light a fire in a field to distract authorities while he detonated bombs inside the Waseca Junior and Senior High School. His plan was apparently to kill or maim as many students as possible before killing himself. He’s due back in court on May 12th.
