In an era of school shootings, sophomore Alex Hribal brought knives.
The 16-year-old boy used two 8-inch knives during a vicious attack Wednesday morning at a high school near Pittsburgh, PA, stabbing and slashing 21 fellow students and a security guard, the Pittsburgh Post Gazette reports.
“When I saw a kid bleeding on the ground is when I realized this was really serious,” student Hope Demont told the Pittsburgh Post Gazette.
Hribal, who was treated for minor hand wounds, was charged as an adult following the attack. Four of his classmates were in critical condition Wednesday evening.
