CAMBRIDGE, Neb. (AP) — Two 18-year-old students accused of planning to attack a high school in south-central Nebraska have been sentenced to probation.

Television station NTV reports Aron McMains, of North Platte, and Joseph Williams, of Oxford, were sentenced Monday to one year of probation after pleading no contest to misdemeanor third-degree assault. They previously were accused of terroristic threats but the charges were lowered in exchange for their pleas.

Court records say Williams, McMains and two 17-year-old boys had for months discussed an attack on Cambridge High School. They tried to recruit another student when one student transferred to a different school.

One of the students told police he thought the plan was a joke but wasn’t sure whether the others felt that way.

Both 17-year-olds are seeking to be prosecuted as juveniles.
