The doors are reopening at the Murrysville high school where 21 students and a security guard were injured in a stabbing rampage five days ago.
Teachers will return to work Monday at Franklin Regional School District. Students will be able to visit the school with their families on Tuesday and classes will resume Wednesday, a week after the attack.
Authorities say 16-year-old Alex Hribal attacked his fellow students at the school with a pair of kitchen knives. He faces four counts of attempted homicide and 21 counts of aggravated assault.
Police and Hribal's attorney say they don't yet have a motive for the rampage. The attorney is seeking a psychiatric evaluation for Hribal.
Four students remained hospitalized Sunday, all in critical condition.
Doctors say a 17-year-old student who was among the most critically injured in the stabbing rampage continues to improve after undergoing another surgery.
The University of Pittsburgh Medical Center said Sunday that the surgery went well. It didn't mention the student by name, but says he's still listed in critical condition.
Spokesman Rick Pietzak says it's the student's fourth and last scheduled surgery.
Seventeen-year-old Jared Boger is among four students still hospitalized following Wednesday's attack at Franklin Regional High School. He's at UPMC Presbyterian, while three others are in critical condition at Forbes Hospital.
