In their newest collaboration, Jaclyn and co-author Glenn W. Muschert provide a critical retrospective of the 1999 Columbine High School shootings as the 20th anniversary approaches. Columbine was a watershed event that changed the way America views mass shootings, both in and out of schools. In this book, the authors will consider Columbine's impact on public opinion about mass shootings, school security, law enforcement practices, threat assessment, legislation, and more. In addition to considering the changes made in the past 20 years since the shooting, the authors also offer consideration of how the nation continues to move forward as we surpass this milestone anniversary.
This award winning book by Jaclyn and co-author H. Jaymi Elsass provides readers and researchers with a critical examination of mass shootings as told by the media, offering research-based, factual answers to oft-asked questions and investigating common myths about these tragic events. The book also addresses common myths associated with mass shooting events by the media, such as how often and where they occur and the absence of any warning signs and helps readers understand the realities of these events, including their international reach, the potential warning signs, and how evidence associated with the events can provide clues into why they occurred.

Welcome to the website of Jaclyn Schildkraut, national expert on mass shootings research

Jaclyn is an Associate Professor of Criminal Justice at the State University of New York (SUNY) at Oswego. Her research focuses on school and mass shootings in the United States in regard to crime statistics, media representations, security and prevention, legislative responses, and other important considerations that impact individuals and communities struck by these tragedies. She has published in numerous academic journals, and her research has been cited by the news media locally, nationally, and even internationally.  She prides herself on providing an honest and genuine account of these events and their impacts, and is grateful for the opportunity to work with communities impacted by these events, including working with individuals from Columbine, Virginia Tech, Sandy Hook, and others. A former resident of Orlando and the Parkland area, each of which has experienced its own mass shooting (Pulse Nightclub, 2016 and Marjory Stoneman Douglas High School, 2018), Jaclyn is committed to helping change the narrative about these events and encouraging a proactive approach to safety and prevention.


Curriculum Vitae


Jaclyn's current research is focused on the effects of lockdown drills on students, faculty, and staff members in schools. Since August 2018, she has been working in Syracuse City School District implementing and testing an emergency response plan to understand how participating in lockdown drills impacts these groups, as well as how training and continued practice impacts the effectiveness of lockdown response. The initial report has been submitted to the district and two journal articles co-authored with Amanda Nickerson stemming from the work have been published in Journal of School Violence and Victims & Offenders. The work also has led to a project with MIT Press, with the book due out in late 2021 or early 2022.

In addition to this work, Jaclyn also has recently published several new journal articles. Her most recent article "Mass Shootings, Legislative Responses, and Public Policy: An Endless Cycle of Inaction" is now available in the Emory Law Journal. Co-authored with Collin Carr, this piece explores two common legislative responses after mass shootings - assault weapons bans and universal background checks - at both the federal and state levels and whether such laws have been successfully enacted.

Jaclyn also recently published "The Survivor Network: The Role of Shared Experiences in Mass Shootings Recovery" in Victims & Offenders with co-authors Evelyn Sokolowski and John Nicoletti. Based on interviews with 16 individuals impacted by the 1999 Columbine High School shooting, this paper explores what resources individuals who are affected by mass shootings seek out during their recovery process and what impact, if any, these have in helping them navigate their trauma.

Jaclyn's research has been featured in a number of national news sources in the aftermath of mass shootings, including the attacks at the New Zealand mosques, Tree of Life Synagogue in Pittsburgh, Santa Fe High School, YouTube HQ, Marjory Stoneman Douglas High School, Route 91 Harvest Festival, Pulse Nightclub, Umpqua Community College, and others. Some examples include:

In the aftermath of the April 3, 2018 shooting at YouTube headquarters in San Bruno, CA, Jaclyn worked with major outlets both in the US and internationally, including CBS News, BBC, The Lily (published by the Washington Post), iHeartRadio Canada, and more. The rarity of female mass shooters was the key topic of discussion in these interview.

With breaking news of a shooting at Marjory Stoneman Douglas High School in Parkland, FL on February 14, 2018, Jaclyn worked with news outlets around the country and the world discussing issues including the No Notoriety campaign, legislative responses, and systems failures. Her work was highlighted by Al Jazeera, The Globe and Mail (Canada), CBC, Vox, and Politifact, among others.
