Prosecutors are asking a state appeals court to reinstate attempted murder charges against a teenager accused of plotting a school attack in southern Minnesota.

The appeals court holds a hearing Wednesday in the Waseca County case.

A judge in July dismissed four counts of attempted murder and two counts of attempted damage to property against the teen, now 18 years old. The judge allowed six counts of possession of explosives to stand.

The teen was arrested in April after authorities said they found him with bomb-making materials in a storage locker in Waseca. Court documents say they also found guns, explosives and a journal that outlined a plan to kill his family, then go to Waseca Junior and Senior High School and "kill as many students as he could."
