BALTIMORE — A 25-year-old substitute teacher stabbed the principal of a middle school in the leg with a butcher knife, then chased him into another office, where he tried to attack an assistant principal before a parent wrestled him to the floor, police said.
Principal G. Roger Proudfoot, 47, sustained a superficial wound in the Tuesday attack, which apparently was provoked when the school told substitute Terrance Leroy Alter that he would not be working there again.
