School Shooters: Who Are They and How Can They Be Identified?

Ever since the attack at Columbine High School in 1999, school safety has been a national concern. The ongoing
occurrence of school shootings is a critical issue for professionals in mental health because they are often in positions to assist with maintaining safety. Knowing the warning signs of impending violence is essential for psychologists in public schools, college counseling centers, private practice, and other settings, so that they can identify potential perpetrators before there is a mass attack. Similarly, administrators and policy-makers need to be educated in best practices regarding threat assessment and the prevention of school shootings.


Dr. Peter Langman is a psychologist whose research on school shooters has received international recognition. His book, Why Kids Kill: Inside the Minds of School Shooters, was named an Outstanding Academic Title and was translated into German, Dutch, and Finnish. His work has been cited in congressional testimony on Capitol Hill and he has been interviewed by the New York Times, The Today Show, 20/20, Nightline, Fox, CNN, the BBC, and over 350 other news outlets in the USA, Canada, South America, Europe, Asia, Australia, and the Middle East. After the Sandy Hook attack, the CEO of the American Psychological Association presented Dr. Langman’s recommendations on school safety to President Obama. He has presented at the FBI National Academy in Quantico, been hired by Homeland Security to train professionals in the United States, and recruited by the State Department to speak to international audiences.  He maintains the largest online collection of materials relating to school shooters at, including over 400 documents totaling 60,000 pages. His latest book is School Shooters: Understanding High School, College, and Adult Perpetrators.
