MARION, ILL – A Marion man has been arrested for making threats against a school.

21-year-old Treston Miller was taken into custody by Marion Police on Tuesday for making terroristic threats.

Investigators say he made online threats to shoot-up a Marion school. During a police interview, Miller admitted that he posted the threats.

It’s not the first time Miller has displayed erratic behavior. In January he interrupted a Marion City Council meeting, running to the front of the room, shouting obscenities, claiming he was wrongly arrested days prior.
