The Pennsylvania teen accused of stabbing more than 20 people at his high school wrote a note saying he couldn't wait to see the ''helpless looks'' on his victims' faces, according to a new criminal complaint filed Friday in the case, according to CNN.
The 20 students and one adult stabbed were all being treated for their injuries, CNN reported. Alex Hribal, the 16-year-old alleged attacker was eventually disarmed, handcuffed and taken into custody.
Authorities looking through his locker found a document dated April 6, three days before the mass stabbing, which signaled Hribal's intentions to kill, according to the criminal complaint, according to CNN.
One part of it read: "I can't wait to see the priceless and helpless looks on the faces of the students of one of the 'best schools in Pennsylvania' realize their previous lives are going to be taken by the only one among them that isn't a plebeian," CNN reported.
On Friday, Westmoreland County District Attorney John Peck told CNN that Hribal is charged with 21 counts of attempted homicide, in addition to 21 counts of aggravated assault and having a weapon on school property.
Hribal was denied bond after the new charges were filed, Murrysville Police Sergeant Charles Tappe said, adding that Hribal remains in Westmoreland County's juvenile detention center even though he has been charged as an adult, according to CNN.
The teenager stands accused of rampaging through the halls of Franklin Regional Senior High School early on the morning of April 9, using a pair of 8-inch kitchen knives to slash those in his path, CNN reported.
His parents and classmates insisted afterward that they didn't see the horror coming, with lawyer Patrick Thomassey describing him as a well-liked and "typical young kid" who had "never been been in trouble," according to CNN.
