Public Statistics

In 1992, Dr. Mike Aamodt started to collect and code data on serial killers. Today, the database is the largest non-governmental serial murderer database in the world. It contains 3304 subjects, comprising of serial killers, mass murderers, spree killers and more. The database has over 9000 victim profiles and over 500 documents. There are over 175 variables per subject, including background information, victim preference, victim treatment and information about the crimes committed.

The information gathered is from public documents including websites, books, court documents and government agencies. Data is available in both a case study format and as ready-to-use statistical information.

Reliable: We provide sources for each data point, which allows the researcher to evaluate how trustworthy each variable is for each subject. We will never knowingly infringe on copyright laws or the copyright holder, and will always give credit where credit is due.

Flexible: The definition of a serial killer has been under debate since the word "serial killer" was first coined. Because of this, we provide easy filtering to allow the researcher to tailor their search to match their particular definition. Filtered variables include victim count, length of killing career, motive, killing method and victim preference.

Peer-Review: Users are encouraged to submit suggestions on all data points in the Database or add new information. These submissions are then reviewed by a team of graduate students with advanced research experience.

Goals: Utilizing Radford's Serial Killer Database as a starting point, the new collaboration is working in conjunction with other Universities to maintain and expand the scope of the database to also include spree killers and mass murderers. Utilizing over 175 data points, multiple-murderer methodology, victimology and statistical analysis; researchers and Law Enforcement Agencies can build case studies and statistical profiles to further research the Who, What, Why and How of these types of crimes.

Membership for the Radford/FGCU Serial Killer Database Project is only offered to those who are pursuing recognized academic research. Applicants must provide credentials from an accredited University or a law enforcement agency and state what reason they have to access the Database.
