A preliminary hearing for the 16-year-old boy charged in the April 9 knife attack at Franklin Regional High School in Murrysville has been postponed.
At the request of his defense attorney, a preliminary hearing for Alex Hribal is now scheduled for June 4 at the Westmoreland County Courthouse.
The proceeding was originally set for April 30 but was moved to May 9 after prosecutors added 17 counts of attempted homicide. The Franklin Regional sophomore is accused of slashing or stabbing 20 students and a security guard before the start of classes April 9.
He has been charged as an adult with 21 counts of attempted homicide, 21 counts of aggravated assault, and a count of bringing a weapon on school property. He is being held in the Westmoreland County juvenile detention center.
In a related matter, two of the injured students remain at Forbes Hospital in fair condition today: Connor Warwick, 16, and Greg Keener, 15, who was moved back into the intensive-care unit Sunday for monitoring, a hospital spokesman said.
