Kent Kiehl from the University of New Mexico, says, “one in one hundred people is a serial killer” A deep experiment and deep understanding definition of a serial killer varies from brain functions, and how the different compartments work with each other to make the person who they are. From a start the separation from a serial killer to an average person begins with the Amygdala, two nuggets of tissue one at each half of the brain, this is the Brains Central Command Center, yet they are no bigger than a thumbnail, and is what processes the emotions of any act the human has committed. Research has now proven that there is another part of the brain that helps the Amygdala processes and respond to the actions, Is called the Frontal Lobe, one out of five lobes and this lobe helps to reason, make judgments, make plans for the near and far future, take action and problem solving. When the Amygdala and the Frontal Lobe work together, they send out signals to the body to react to certain situations, which not only varies from Serial Killer to an average person, it also varies from people to people. The function of these two parts of the brain, is what causes a person to feel guilty when they did something wrong, from stealing a cookie from the cookie jar to the first time skipping school and get caught. For example, if somebody had purposely broken a window, a state of panic comes into play and the person feels guilty, no matter how much they apologize, they still have the constant thought of “oh no, what have I done?”, however Serial Killers don’t have the state of panic. The Studies have shown that the Amygdala and the Frontal Lobe of the body, don’t necessarily communicate as properly like those of average people and that a Serial Killers Amygdala is 17% smaller than most people, making it a very crucial piece of information to understand why Serial Killers are not afraid and lack the conscious to commit evil acts. Keeping in mind that parts of a Serial Killers brain is smaller it doesn’t mean they are caught by lack of intelligence, some Serial Killers like Joel Rifkin have an Intelligence Quotient (IQ) of 128, placing him on the top three percentage of the population.
The Federal Bureau of Investigation (FBI) has been conducting test separating to what they believe a Serial Killer wants out of the crime. What they believe they are trying to investigate how to deeper understand and figure why a person kill, out of pure satisfaction; although, they are questions still to be answered, they have categorized Serial Killers into four broad typologies. The Identifying of Serial Killers and the four typologies was introduced by Ronal M. Holmes and James E. De Burger in 1985: visionary, mission, hedonistic and power/ control. According to Holmes and De Burger Power/ Control killer are motivated to kill to satisfy their desire for domination and control over their victims, they will show signs of planning and controlling the crime scene in with other modus...
