Lancaster County authorities will charge 16 year old Sarah Piccolo as an adult with felony assault and use of a deadly weapon.

She was taken into custody on Tuesday in Woodson County, Kansas by officers responding to a report of someone with car trouble.  Piccolo has waived extradition proceedings and is expected to return soon to Nebraska.

The stabbing attack occurred Monday morning inside a bathroom at the school.  17-year-old Ellen Kopetzky suffered cuts to her face and was released from a hospital after surgery.
