The stabbings were reported at Franklin Regional High School, in the suburb of Murrysville. Ambulances swarmed the parking lot.

The charges might not reflect all victims, according to Westmoreland County public safety spokesman Dan Stevens. Two other students were treated for injuries that were not from being stabbed.

Mr. Peck told the court that the suspect made some statements after school officials tackled him that indicated he wanted to die.

Defense attorney Patrick Thomassey described his client as a good student with no prior criminal record and no history of addiction to drugs or alcohol. He said his client is not a loner and interacts well with other students.

Mr. Thomassey described the incident as “bizarre” and asked for a mental evaluation to determine whether his client will be competent for an April 30 preliminary hearing.
