Catholic officials knew of teacher's abuse, court files indicate

The Catholic-school teacher had a pre-teen student pinned to the ground in his Baltimore classroom, the girl's blouse open and her chest exposed when the doorknob suddenly turned and the school principal — a nun — burst in.
The screaming girl thought she was about to be rescued, according to court records that describe the scene at the Catholic Community Middle School in Locust Point. But Sister Eileen Weisman, who had a key to the room, merely chastised the teacher, John Joseph Merzbacher, for locking the door.
