Alex Hribal, the teen suspect in the shocking Pennsylvania stabbing case, may have offered up an explanation for his violent attacks after all.

In a note recovered by law enforcement officials, the 16-year-old allegedly wrote that he couldn’t wait to see the “priceless and helpless looks on the faces of the students of one of the ‘best schools in Pennsylvania’” after he killed them.

The note was apparently signed and dated a mere three days before Hribal showed up to the Franklin Regional High School in Murrysville, Pa. and started stabbing his fellow students.

According to an affidavit, Hribal wounded 20 students and a security guard during the school stabbing incident that occurred roughly two weeks ago.

Aside from this portion of Hribal’s note, nothing else written has been released to the public.

This small section letter is hugely significant as it seems to show the state of mind of the suspect ahead of the violent attacks.

The teen has been charged with numerous counts of attempted homicide, and no doubt this signed note will act as a huge piece of evidence in the case against the suspect.

Patrick Thomassey, a defense attorney for Hribal, declined to comment regarding the note’s content, specifically the fact that the words directly contradict his claims about how the suspect felt about his actions.

Thomassey painted his young client as a frightened teenage boy who was remorseful about what he had done to so many people.

The note paints a remarkably different picture of Hribal. It shows him as almost gleeful about the deaths he intended to cause.

Vice-principal Samuel King said that Hribal had refused to drop the knives during the attack. Allegedly Hribal responded by saying, “No, I am not dropping them, my work is not done, I have more people to kill.”

With eyewitness accounts and his own words to be used against him, it may prove impossible to get Hribal’s case transferred to the juvenile court, which was Thomassey’s intent.

As of now Hribal has been charged as an adult with no less than 20 counts of attempted murder and 21 counts of aggravated assault.
