PITTSBURGH (KDKA) -- Court documents released Wednesday reveal several items investigators seized from the school locker of the teenage suspect in the stabbing attack at Franklin Regional High School in Murrysville.
They include a backpack, cell phone, a handwritten note, several binders, a text book and a plastic bag with gym clothes.
No one has released the contents of the handwritten note.
Alex Hribal is accused of stabbing 21 people inside the high school earlier this month.
He is charged as an adult and is undergoing a psychiatric evaluation.
A motive behind the stabbings is still unknown.
Meanwhile, two of the most seriously injured victims of the stabbings are now out of the hospital.
Jared Boger, 17, was discharged from UPMC Presbyterian Hospital Wednesday afternoon.
He had been on life support immediately after the attack.
A 16-year-old student was also released from Forbes Hospital this evening, according to the Allegheny Health Network.
That leaves two students who are still hospitalized. They are both being cared for at Forbes Hospital, one remains in critical but stable condition and the other is in fair condition.
