The teenager accused of plotting to kill his family and set off bombs at his school will be charged as an adult.
John David LaDue, 18, will be moved from the juvenile facility where he is being held to Waseca County Jail until a hearing can be scheduled.
"Adult certification will serve public safety and meet the needs of the child for treatment and rehabilitation," Waseca County District Court Judge Robert Birnbaum ruled on Friday.
LaDue was found in April 2014 with bomb-making materials, guns and a detailed notebook that laid out his massacre plans. He was 17. At one point he faced attempted murder charges, but a court dismissed those charges and other serious counts against him, finding that he hadn't taken steps substantial enough to warrant them.
He still faces six charges of possessing explosive devices. If convicted as an adult on all six charges, he would face a guideline sentence of 60 months in prison, Waseca County Attorney Brenda Miller said.
Miller declined to comment on Friday's certification order, and LaDue's attorney, Dawn Johnson, did not respond to a request for comment.
Several factors play into whether a juvenile will face charges as an adult, including the seriousness of the offense, any prior record and the adequacy of punishment or services available in the juvenile justice system.
LaDue has multiple mental health diagnoses including Asperger syndrome. He'd be eligible for intervention and monitoring in the juvenile system until his 21st birthday — about 30 months from now.
