An emergency message on the school district's website reads:
"A critical incident has occurred at the high school. All elementary schools are cancelled, the middle school and high school students are secure. Additional information will be released as soon as possible. Please keep our campus clear of traffic.
At this point, all we know about the suspect is that he or she is a student at the school. According to Dan Stevens with Westmoreland Emergency Management, at least 20 people were stabbed or otherwise injured in the incident, four of them seriously. Later on Wednesday morning, the CEO of Forbes hospital confirmed to WTAE that it was treating 8 victims — seven students and one adult — of the 20 total. Half of those at Forbes had what were characterized as "life threatening" injuries, although all are expected to survive their injuries. That's in part thanks to the efforts of one student at the scene:

Ten other students were hospitalized at other nearby hospitals, WTAE added, but there's little information on their status.
One student gave a short, albeit unconfirmed, account of the incident to WTAE:
A student reported that someone came into the school with a knife and started slashing people, including some of his friends. That information has not been confirmed by police.
According to WTAE, school has been cancelled for the day following the incident, and officials are working on a plan to get send students back home.
