A serial killer is a person who has committed several criminal murders separated by time (“cooling off period”) for more than a month. The exact number of victims, which is the minimum for establishing the fact of the presence of a serial killer, differs in different sources. According to some of them, the minimum number for qualifying a criminal as a serial killer is three murders. At the same time, for example, the FBI does not take into account the criterion of “three or more” and defines seriality as “two or more murders committed as separate cases, usually, but not always, by a single lone attacker” or, including essential characteristics, at least two kills. Serial killers are motivated by a pathological desire to satisfy their perverted desires. Many serial murders involve sexual intercourse with victims, but the FBI notes that anger, agitation, financial gain, or attention may be the reason for the emergence of a new serial killer. Killings can be arbitrary or prepared, just as victims can have something in common: race, appearance, gender, age, etc. A serial killer is not identical to a mass murderer, since the latter commits his crimes within a short period of time in two or more places, without any interruption. However, cases of continued killings over weeks and months without interruption ("cooling off periods") or "returns to normal life" have led some experts to suggest a mixed variety of "serial-mass killer".
