55% (N = 58) experienced psychosocial stress with 106 murderers with ASD and / or head trauma

Multiple and continuous killing is a rare event with a very serious social impact. In accordance with the PRISMA guidelines, we have conducted a systematic review of peer-reviewed literature, news, relevant organization legal sources and serial killings. Our findings suggest that these extreme forms of violence may be the result of a very complex interaction of biological, psychological and social factors. Symptoms are disorder or head trauma. Studies of several consecutive murder cases have just begun: the lack of rigorous research, most of the literature is anecdotes and speculation. Specific future studies on the potential role of neurodevelopmental disorders in numerous ongoing murders are needed and innovative research techniques may be required due to the scarcity of these events.

Continuous murderers and mass killers Mass killers and homicide murderers are novelty for today's society. These malicious murderers are violent and barbaric monsters and have an unusual killing desire. What forces the urge to kill people urged them to keep killing. Whether these killers are satisfied with the murder. Is there any difference between a mass killer and a serial killer, or whether they are the same or not. How do they choose victims and some of their characteristics? - Numerous people, especially criminologists, spend a lot of time investigating serial killers as they are very attractive. Criminologists are keen to catch them before killing, which is why they study them in such a deep way. Many people do not agree with the definition of serial killings. The US Federal Bureau of Investigation has defined it as "he killed two or more criminals illegally in the same incident" (9).

Continuous killings are defined by three key elements: quantity, time, and motivation. Most murderers have only one victim; by definition, a serial killer has multiple victims. The minimum number of victims listed in the various definitions of recent serial murder cases ranged from 2 to 10 and the modal value was 3. The time factor of the serial murder case was designed to distinguish continuous killers from mass killers and carnival killers. . Mass killers have multiple victims in one episode and Carnival Killer has multiple victims in several independent but related cases, but in both cases the emotional between murders There is no confusion. On the contrary, in a continuous murder case there is cooling for days, weeks, months or years. Finally, in order to distinguish continuous killers from professional strikers, political terrorists and military combatants, most of the serial killings omit the definition of killing people for financial, political or military benefits did.

All serial killers are murderers, but not all murderers are continuous killers. There is a big difference between a murderer and a serial killer. "Continuous murderers kill at least three victims one at a time in a series of consecutive murder cases with psychological satisfaction as the main motive" (Smith, 2003). Among them, the main difference is listed. The main motivation of continuous killers is psychological satisfaction with behavior, and the average killing may be due to reasons such as revenge and robbery. A typical serial killer profile is a 20-30 year old white male who is usually targeting a victim near the living space. There is usually a cooling period before another killing occurs, but as the crime approaches it is clear that the murderer reaches its peak and needs more to stimulate his psychological desire. This is a typical configuration file, exceptions to this rule.
