STATEN ISLAND, N.Y. — School Safety Agent Peter Mattera was at his usual post outside Tottenville High School Tuesday afternoon for dismissal when he heard multiple gunshots in his area.

He rushed toward the scene, just dozens of feet from the school’s entrance, and put a call over his radio that there were possible shots fired. When the victim, a 14-year-old boy, hit the ground just across the street from him with blood coming from his ankle, he jumped into action.
