One of the oldest questions in Criminology is “Are Criminals Born or Made?”

Many serial killers are survivors of early childhood trauma of some kind – physical or sexual abuse, family dysfunction, emotionally distant or absent parents. Trauma is the single recurring theme in the biographies of most killers Asa consequence of this trauma, they suppress their emotional response. They never learn the appropriate responses to trauma, and never develop other emotions, which is why they find it difficult to empathize with others.

Research shows that certain genes can predispose people to violence.Many serial killers experiencechildhood trauma or early separation from their mothers. As a consequence of that trauma or separation, scientists believe, they learned to suppress empathy or suffered damage to the areas of the brain that control emotional impulses. Serial killers often are loners who fear all relationships and seek to control, to destroy other people to eliminate the possibility of another humiliating rejection.Those who've studied serial killers believe that many are at least partly motivated by the attention and fame that mass media can provide mass murderers.

SERIAL KILLER VICTIM SELECTION

"No one knows for sure why a serial killer will choose a certain individual as their victim. When asked why, serial killers often give a wide range of answers regarding the reasons for their murders. The most common belief is that the killer wants to feel complete control over another person. They thrive on the fear their victims display and see the murder as the ultimate form of dominance over a human being.

Research Guides: How to Spot a Serial Killer: History of Serial Killers (2)

"In order for any person to be defined as a serial killer, they must satisfy a few criteria, specified by the Federal Bureau of Investigation. The personin question must have murdered a minimum of three individuals (not simultaneously), there must be a period of time in between the murders (to prove that multiple victims were not killed during a single fit of rage), and the circ*mstances of each murder should indicate that the killer felt a sense of dominance over the people they have killed. The victims must also be vulnerable to the killer in some way, a characteristic which indicates that the killer has sought to achieve a feeling of superiority.

"Many experts agree that serial killers have a vision in mind of their victim. This person would be thought of as their “ideal victim” based on race, gender, physical characteristics, or some other specific quality. It is rarely possible for the killers to find people who meet these exact qualifications, so they generally seek out people with similar traits. This is why serial killings often seem to be completely random at first – each victim may have something in common that only the killer easily recognizes.

"It is generally accepted that most serial killers feel a strong urge to commit acts of murder. They are, however, thought to be extremely cautious people who will not choose a victim unless they feel the chances of success are very high. For this reason, the first murder victim is very often a prostitute or homeless person, someone the killers can attack without drawing a lot of attention. These factors make it even more difficult to establish patterns in a series of slayings and to track down the responsible culprit."
