Prosecutors are seeking adult charges for a southern Minnesota teen who authorities say had planned to kill his family and bomb the junior and senior high school in Waseca.
KTOE-AM reports that Waseca County prosecutors filed a motion Friday, asking that the teen be charged as an adult. A hearing is set for May 12.
Police arrested 17-year-old John La Due this week and charged him in juvenile court with multiple counts of attempted first-degree murder, possessing explosive or incendiary devices and criminal damage to property.
A juvenile petition says he told police he intended to kill "as many students as he could."
Police Capt. Kris Markeson says an "unimaginable tragedy" was stopped. Police say they believe the teen planned to carry out his plan in the next few weeks.
Chelsie Schellhas lives next to the storage unit where authorities found LaDue Tuesday night.
She saw him walk through her backyard, open the storage locker and close the door behind him. Schellhas called 911.
"I wouldn't call me a hero. I don't feel like I should take that name, I didn't take the bomb out of his hand. I just I'm the one who called it in for being something I thought was minor... I'm just happy that I could have saved my family and other people's families," Schellhas said.
Schellhas' phone call prompted officers to check on the storage unit. LaDue was taken into custody a short time later.
"It's a small town, something that horrific is going to linger for a long time," Schellhaus said.
A meeting was called for Friday afternoon by Waseca schools to calm parent and student fears. Kids will return to school Monday.
Waseca schools was in the middle of several security changes across the district.
Hartley Elementary got a new visitor management system six weeks prior that swipes visitors' drivers license and prints a label. Hartley was also installing a magnet lock system and a panic button at the school front entrance Friday.
The district has also been planning on hosting a three day training session for district administration with Homeland Security on school safety at the end of June. In July, the Waseca Police Department had planned on holding an active shooter training session for the administration.
Staff at Waseca schools will start using a security app called "Crisis Go," that installs all emergency plans for educators, in the fall.
