By far, the best tool a Citizen Detective has is the internet and all of the publicly available data at your fingertips. From social media platforms to message boards to public archives, so much information exists that can be used to connect dots.
The best place to start your detective work is to examine the most complete data on U.S. homicides available, The Murder Accountability Project. Here you can navigate to see trends in the types of murders, location of murders, and demographic information on victims.
This site is valuable to test hypotheses about murder suspects that could have been killing for a long time in one jurisdiction or in a variety of locations.
Using an algorithm, The Murder Accountability Project has also developed Murder Clusters. These datasets are capable of identifying serial killers murdering multiple victims with identical killing techniques within a particular geographic region. This method can be helpful to spot difficult-to-see trends over a span of several years or longer.
While not every case is the result of a serial murderer, identifying patterns and providing a new perspectives are some of the key benefits of Citizen Detective work. Here are other databases that are helpful bookmarks to uncover patterned information:
