Sabrina Milo: Brooklyn, New York

Milo was arrested for allegedly making "Columbine-like" threats while teaching at a Brooklyn high school. Milo reportedly told other teachers she would bring in a "machine gun under a trench coat and it would be Columbine all over again." When he heard of the incident, Milo's husband's ex-wife reportedly said, "I'm shocked, but I'm not surprised."
