School Shooters: Understanding High School, College, and Adult Perpetrators

Dr. Langman’s new book builds on the research presented in Why Kids Kill, but has a vastly expanded magnitude:

  • The sample of shooters has grown from 10 to 48.
  • The book investigates school shooters through the lifespan, from age 11 to 62.
  • It includes attacks not only from the USA, but also 10 rampages from 5 other countries (Canada, Germany, Finland, Scotland, and Brazil), providing an international scope.
  • Though most shooters are males, the book includes profiles of 4 female shooters and compares them to male perpetrators.
  • The chronology of attacks extends from 1966 through 2012.
  • The 48 shooters are grouped into three populations: secondary school shooters, college shooters, and aberrant adult shooters.

The expanded range of this work allows for numerous comparisons and analyses, providing answers to many questions:

  • Were most shooters really white males? Middle class? Loners?
  • Who were the most frequently targeted victims?
  • Which type of shooter was most common?
  • Which shooters were the most deadly? The most suicidal?
  • Which type of perpetrator experienced the most peer harassment?
  • Which committed the most peer harassment?
  • What life experiences put them on the path of violence?
  • What did the shooters have in common, regardless of their type or population?

In addition, the book addresses threat assessment and the warning signs of potential violence, highlighting pre-attack behaviors that signaled impending rampages. Examples are given of warning signs from actual attacks, including:

  • those heard by peers
  • school assignments that foreshadowed attacks
  • indications at home of potential danger
  • warning signs online

It also examines the aftermath of shootings:

  • How did the attacks end?
  • What did the perpetrators do when confronted by law enforcement?
  • What do first responders need to be prepared for when dealing with a rampage shooter?
