Sarah Piccolo, School Stabbing Suspect, Wanted 'To Kill As Many People As She Could': Prosecutor

Lincoln Police

A 16-year-old girl accused in a brutal stabbing at a Lincoln, Neb., Catholic school last month will be prosecuted as an adult.

Sarah Piccolo is charged with first-degree aggravated assault and use of a deadly weapon stemming from the incident, in which she allegedly ambushed Pius X High School senior Ellen Kopetzky in a bathroom Oct. 7.

Police said Piccolo cut Kopetzky's face several times with an 8-inch hunting knife, and hit her in the back of the head with a claw hammer, according to the Lincoln Journal-Star.

On Tuesday, the newspaper reported that Piccolo will face trial as an adult, a move put forward by prosecutors at a hearing last Friday.

In court Nov. 15, Deputy Lancaster County Attorney Bruce Prenda argued against transferring Piccolo's case to juvenile court, saying she had attacked the first student that happened to come through the bathroom door.

“This was a very troubled 16-year-old girl, and no one anticipated this behavior,” Prenda said in court, noting that there had been no evidence the suspect had been treated badly at home or at school. "Her motive was to quite simply kill as many people as she could."

As the prosecutor spoke, Piccolo hung her head and sobbed, according to

According to police reports, there was no connection between the students that would explain the assaults. Witnesses told police that Piccolo did not say a word before, during, or after the assault.

After the attack Piccolo fled in her boyfriend's car, but surrendered to police in Kansas a day later. She pleaded not guilty to the charges. Kopetzky survived the attack and returned to school a week later.

The defense argued that the incident was "a huge cry for help," and argued for Piccolo to be tried as a juvenile, but the judge did not agree.

If convicted, Piccolo could face "a minimum of one year in prison to a maximum of 50 years on each count," according to
