MURRYSVILLE, Pa. (AP) - Teachers are returning to work today at Franklin Regional High School near Pittsburgh, following last week's stabbing rampage that left 21 students and a security guard wounded.
Classes will resume Wednesday.
Authorities say 16-year-old Alex Hribal attacked his fellow students at the school with a pair of kitchen knives.
Four students remain hospitalized in critical condition.
