Dr. Amy Bishop

When you think of a stereotypical school shooter, you probably don’t picture Dr. Amy Bishop, a middle-aged mother and biology professor. In 2010, she executed three of her colleagues at the University of Alabama in Huntsville (UAH), where she had recently been denied tenure. Initially, many thought Amy had just “snapped,” but investigators discovered that she had a history of workplace problems, and this wasn’t the first time that she had killed someone.
