For the past 2 years, Dr. Peterson and Dr. Densley have been leading a research study, funded by the U.S. Department of Justice, examining the life histories of hundreds of mass shooters since 1966.  Using publicly available data, records, and interviews with incarcerated perpetrators and people who knew them, they have created a public database to drive effective policy. This presentation will explore the patterns in the lives of mass shooters and present a data-driven framework for prevention.
