The Deadliest Female Mass Shooters in Modern American History

As Investigators learn more about the fatal shooting at YouTube's San Bruno, Calif., campus, one detail stands out: The shooter was a woman. The majority of mass shooters in the United States are men, but female mass shooters are not unheard of. One of the deadliest female mass shooters in modern American history was Tashfeen Malik, who killed 14 people with her husband in San Bernardino in 2015. Another was Brenda Spencer, a teen who shot several schoolchildren and killed two adults in 1979.
