Killer.Cloud the Serial Killer Database, an ongoing research project which aims to sort and classify serial killers based on documented references from books written about serial killers as well as other online resources listed at the bottom of each killers profile page. Some serial killers on this list may be unidentified or using an alias as their main name, alphabetical order is a very loose term. Also consider that in many parts of Asia, as well as some parts of Europe and Africa, the family name is placed before a person's given name. In these cases, for simplicity, we have used the last section of the name.
