Serial Killer

A serial killer is a serial killer. He is also a criminal murderer that he reiterates in time. According to the most common definition, this type of criminal has committed at least three murders, in a period of time - from a few days to several years - separating each of these crimes. It seems, in some cases, to derive some degree of pleasure from killing one's victims. A serial killer is usually characterized by the fact that there is no connection between him and his victim. In other words, he does not know his victim before choosing it, which makes it more difficult for the investigators to find the perpetrator. That's why police and gendarmes will use the so-called "profiling" technique.
