The 16-year-old boy accused of stabbing at least 21 people at his Pennsylvania high school couldn't wait to see the "helpless looks" on his victims' faces, and refused to drop the two knives he was carrying as he had "more people to kill," according to a new criminal complaint filed Friday.
"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 precious lives are going to be taken by the only one among them that isn't a plebeian," wrote Alex Hribal in a signed note that was found in his locker, according to The Associated Press.
The note was dated April 6, three days before the stabbing at Franklin Regional High School near Pittsburgh.
The teen's charges have been upgraded to 21 counts of attempted homicide. He was initially charged with four counts.
Among his victims was a security guard. Two students, identified as 15-year-old Greg Keener and 16-year-old Connor Warwick, remain hospitalized.
The school's vice principal, Samuel King, who managed to grab the suspect in the hallway and take him to the floor, said Hribal refused to drop the knives saying, "No, I am not dropping them, my work is not done, I have more people to kill."
A preliminary hearing will be held Wednesday at the Westmoreland County courthouse. Hribal is at a juvenile facility since his arrest.
Murrysville Police Chief Tom Seefelt said these details suggest he is a troubled teen, according to WPXI. "He made a statement like that when he was initially caught up that he wanted to do more than he did but fortunately, it came to an end when it did," he was quoted as saying.
The FBI is analyzing computers and video games seized from the suspect's home. "We go through the investigation and see if anything develops. That maybe clears things up for us in his thought process throughout this whole situation," Seefelt added.
Hribal allegedly went on the rampage at the high school in the early morning of April 9 before classes began, and wounded 21 students and the security guard.
"He's a typical young kid. He's a B+ student. The family is like Ozzie and Harriet. They have dinner together every night," attorney Patrick Thomassey earlier told CNN. "All the students liked him. He worked well in groups, and this happened. So there's a reason for it – that's what I'm saying. And we have to get to the bottom of that."
