This document provides brief summaries of the shooters’ negative experiences in educational settings, including academic failures, disciplinary actions, and other issues. It also notes their families’ involvement in education, primarily as school personnel such as teachers or professors. Finally, it identifies those cases in which the shooters targeted specific people at school due to perceived injustices, as well as those shooters whose violence may have been related to their family members’ positions or accomplishments in education.
One way to make sense of school shootings is to examine who the targets were. Though some attacks consisted of indiscriminate violence against anyone in the vicinity, others were partly or completely targeted against specific people. This document lists shooters and notes their targeted victims in five categories: bullies, rivals, family members, girls/women, and school personnel.
This document lists arrests, law enforcement contacts, and reports to the police about the perpetrators of school shootings that occurred prior to their attacks.
This document identifies the sources of firearms used in 52 school shootings (involving 54 perpetrators) during the twenty-five years from 1991 through 2015. The sample includes both single-victim and multi-victim shootings committed by secondary school, college, and aberrant adult perpetrators.
This document presents data in several areas: body-related issues that may have been challenges to the perpetrators’ identities, family members who served in the military and/or law enforcement, the shooters’ aspirations to serve in these professions, and the frequent thwarting of these aspirations. These different sets of data are presented together to explore possible connections between the shooters’ family role models for masculinity, their own possible sense of damaged manhood, and their own striving to be soldiers or police officers. Note: though the focus is on masculine identity, the document also includes female shooters with body-related issues, family members in the military, and military aspirations.
This is an exploration of the issue of influence among school shooters, documenting references by subsequent attackers to those who came before them. It also notes historical figures who may have served as role models for violence. The bulk of the document is a listing of school shooters and their influences, including a diagram of the lines of influence from Columbine through subsequent attacks.
School shooters are often said to always, or nearly always, be “white males.” There is, however, more racial/ethnic/gender diversity among school shooters than is usually recognized. Based on the sample presented in School Shooters, white male shooters were a majority among secondary school shooters, but a minority among the college and aberrant adult populations of perpetrators. This document identifies all the perpetrators listed on this site from the USA, Canada, and Australia who were not white males. (Note: the two Brazilian shooters were Latino but are not listed here because they belonged to the majority culture in their country.)
This document pulls together information on a variety of issues relating to school shooters, including adoption, immigration, fire-setting, marriage, self-injurious behavior, hostage situations, attempts to escape, Nazi interest, satanism, suicide by cop, those who killed family members, and those who have been released from prison. It also covers multiple aspects of sexuality, including those shooters who had a history of sexual abuse, those who committed sexual offenses as part of their rampages, and those who identified as gay/homosexual.
A common misconception about school shooters is that they are typically kids from stable, middle-class families. This document presents information on the families of shooters, including factors such as divorce, domestic violence, child abuse, criminal behavior, and parental alcoholism and drug addiction. The percentage of broken homes and dysfunctional familes is very high.

This is the complete spreadsheet that lists all attributes of all shooters profiled on this site. This document is continually updated to reflect new information, and the data should be identical to those in the School Shooters .info database. Latest revision: 26 September 2017. Note: This is an Excel file. It will download to your computer, not open in your browser. Once it’s downloaded, you can manipulate the rows and columns as with any spreadsheet. Thus, you can rank or organize the shooters by date of attack, age, psychological type, number of victims, or any other variable included in the data.
This document summarizes the medication and substance abuse histories of dozens of school shooters. This is a companion document to the article “Psychiatric Medications and School Shootings.”
This is a timeline of all the school shootings and other attacks included on this site.
These two documents were found online, compiled by an unknown researcher. I have attempted to obtain permission from the researcher to post this material, but have been unsuccessful. I am posting the documents here to preserve this meticulous work. These two documents provide a page-by-page listing of the contents of the first 11,000 pages of JCSO documents.
This document is an index to thousands of pages of documents compiled by the Jefferson County Sheriff’s Office (JCSO) related to the attack at Columbine High School. This is a guide to summaries of hundreds of interviews organized first by the first name of the interviewee and then by the last name of the interviewee. The original document was found online with no indication of who created it. It has been redesigned for this site.
The attack at Columbine generated over 27,000 pages of documents for the Jefferson County Sheriff’s Office (JCSO), most of which have been made public. These include reports from thousands of interviews with people who knew Harris and Klebold, as well as the killers' personal journals, school planners, academic assignments, yearbook inscriptions, and more. I have organized an index to assist people in locating references by theme. For example, there are pages listing references to Harris and Klebold being harassed, as well as references to Harris and Klebold not being harassed, and references to Harris and Klebold harassing others. There are 10 categories divided into additional subcategories.
