List of serial killers by number of victims
A serial killer is a person who murders two or more people, in two or more separate events over a period of time, for primarily psychological reasons. There are gaps of time between the killings, which may range from a few hours to many years. This list shows serial killers from the 20th century to present day by number of victims (list of serial killers before 1900). In many cases, the exact number of victims assigned to a serial killer is not known, and even if that person is convicted of a few, there can be the possibility that he/she killed many more. Due to the complex nature of serial killers, their crimes, discrepancies caused by geographic location and/or time, and the investigations related to these persons results in difficulties in organization and ranking. To address this, multiple categories have been provided in order to more accurately describe the nature of certain serial murders.
