MURRYSVILLE, Pa. (AP) — The doors are reopening at the Pittsburgh-area 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 in Murrysville. Students will be able to visit the school with their families on Tuesday and classes will resume Wednesday, a week after the attack.

Four students remained hospitalized Sunday, all in critical condition.

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.
