A 16 year-old sophomore student at Franklin Regional High School in Murrysville has been charged in the multiple stabbings that occurred at the school on Wednesday morning.
The suspect, identified as Alex Hribal, has been charged with four counts of attempted homicide and 21 counts of aggravated assault.
Reports now indicate that 24 people were injured in the stabbings and in the race for the exit doors that began once a student activated a school alarm to draw the attention of authorities. It appears 21 people sustained stab wounds. Those victims included 20 students and a security guard who attempted to intervene.
As of Thursday morning, 13 of the victims remained hospitalized. A 17 year-old boy was listed in critical condition, while three students remained in intensive care, four were listed in stable condition, and five other students were reported to be in either fair or good condition. The security guard was one of the victims who was not held in the hospital overnight.
Investigators are still trying to determine the motive behind the rampage, but they are reportedly looking into a rumored threatening phone call involving the suspect and another student that reportedly took place Tuesday night. Some students who witnessed the outset of the attack Wednesday morning say they saw a boy brandishing two knives tackle a male freshman student, stab the boy in the belly, and then begin running down a hallway, attacking other students.
