WASECA, MINN. – After more than a year of legal debate over what to do with a Waseca teen accused of planning a massacre at his school, John LaDue pleaded guilty Friday to a single felony count of possessing an explosive device.
Under terms of a plea agreement, LaDue will serve five to 10 years' probation, including an unspecified amount of time at a secured autism spectrum disorder facility before moving to a halfway house and then intensive supervision.
A judge will issue the final sentence in October.
LaDue, now 18, was polite and matter-of-fact as he sat in orange jail garb Friday and admitted in court to possessing an explosive device as a minor, referring to what his attorney later described as a small "cricket" explosive.
In exchange for his plea, prosecutors agreed to drop the five remaining similar counts against him.
The "cricket" explosive was one of several items authorities found when searching LaDue's bedroom and storage locker in late April 2014.
Police were alerted to LaDue by a suspicious resident who called them after seeing the teen enter a storage locker. That night, LaDue told authorities of his plans to shoot his family, then go to school with pressure-cooker bombs, firearms and ammunition. Authorities said they confiscated chemicals, several guns, ammunition and a few completed explosives.
LaDue, 17 at the time, was initially charged as a juvenile with four counts of attempted murder, two counts of first-degree damage to property and six counts of possession of a bomb by someone under 18. But a judge dismissed the attempted murder and property-damage charges, noting that the state had failed to show that LaDue had made a substantial step toward committing the crimes.
