Criminal Psychology: What Does a Serial Killer Look Like?

Serial killer psychology, criminal psychology

Perhaps because of the alarm it generates, its harshness, or the intellectual challenge that its study demands, serial murders have been one of the main foundations of the study of forensic psychiatry since the advent of forensic psychiatry. To date, it has not been possible to definitively establish what the psycho-clinical profile delineating the killer serial of a normal citizen.

We know that the psychological background of a serial killer’s profile is that of a humiliated, abused and abused child. In half of the cases, he has suffered a paternal absence and considers his mother a danger from which he must protect himself.

However, a recent discovery in the New England Journal of Medicine revealed anatomical differences between serial killers and ordinary people. In the serial killer, a larger and therefore more functional frontal lobe is assessed, characteristic that gives them greater aggressiveness and less empathy than average.

In the frontal lobe reside behavior, strategy, working memory and planning capacity. You could say it’s the most “human” part of our brain. Its hypertrophy indicates a strong aggressiveness and, in turn, an increase in strategic capacity as well as a weak capacity for empathy which can lead to a certain risk of sadism.

The neurochemistry of the serial killer

Another distinguishing trait between serial killers and the rest of the population, according to Dr. Reid Meloy, is an abnormally high level of manganese, iron and copper, so that has a direct impact on the decrease in dopamine and serotonin, Which are relaxing substances that lower the levels of testosterone (a hormone that causes not only excessive aggression but the need for domination), so that the individual suffers from a behavioral disorder which leads him to the criminal act in a desperate attempt to impose his superiority on his comrades.

Unfortunately, even with the advancement of this discovery, which brings one closer to the mind of the benchmark serial killer, these clinical findings do not yet predict or prevent the sadistic drive of these subjects.

cal decipher the exact combination of factors that lead to this criminal behavior. Does science have an answer to this challenge? There is no doubt that the answer will perhaps be found in a few years.
