A 14-year-old Hutchinson boy was sentenced to nearly four years in juvenile detention for his role in a plan to launch a pipe bomb attack on Hutchinson High School.

The teenager was sentenced Tuesday to 45 months in detention, followed by three years of aftercare.

Authorities say he and a 15-year-old Hutchinson boy conspired to kill specific staff at the school with pipe bombs. Court documents allege the pair wrote plans for the bombs and used gunpowder from blasting caps to trigger the bomb.

Another student alerted the high school administration of the alleged plot.

Both teens pleaded no contest to a charge of conspiracy to commit capital murder.

The boy apologized to the school, the court and his family for his actions.
