LINCOLN, Neb. (AP) — A teenager convicted of stabbing a classmate in a Lincoln high school bathroom has been given five years of probation.

Online court records say Sarah Piccolo was sentenced Thursday in Lancaster County District Court. She’d pleaded no contest in August 2014 to felony assault after prosecutors lowered the charge.

The Lincoln Journal Star reports that Piccolo has been receiving treatment at an Omaha center as part of a separate, sealed juvenile court case.

Police say Piccolo used a hunting knife and a claw hammer to attack a 17-year-old girl at Lincoln Pius X High School in October 2013. The girl was hospitalized.

Piccolo was 16 at the time but was being prosecuted as an adult. Court records show that she’ll turn 19 Sunday.
