A woman who opened fire in a private Nashville school on Monday, killing three children and three adults, is the first female school shooter to kill four or more people, according to specialists who have tracked decades of mass killing events.
The six victims killed at The Covenant School in Nashville included three 9-year-old students and three adults in their 60s, officials said, including the head of the school. The suspect, a 28-year-old woman who was killed by police, is believed to be a former student.
