Validating technique in psycohology
The Federal Bureau of Investigation (FBI), for example, defines serial killing as "a series of two or more murders, committed as separate events, usually, but not always, by one offender acting alone".
Serial killing is not the same as mass murdering (killing numerous people in a given incident); nor is it spree killing (in which murders are committed in two or more locations, in a short time).
Criminologist Jose Sanchez reports, "the young criminal you see today is more detached from his victim, more ready to hurt or kill ...
The lack of empathy for their victims among young criminals is just one symptom of a problem that afflicts the whole society." Lorenzo Carcaterra, author of Gangster (2001), explains how potential criminals are labeled by society, which can then lead to their offspring also developing in the same way through the cycle of violence.
According to Garrison (1996), "the child becomes sociopathic because the normal development of the concepts of right and wrong and empathy towards others is retarded because the child's emotional and social development occurs within his self-centered fantasies.
A person can do no wrong in his own world and the pain of others is of no consequence when the purpose of the fantasy world is to satisfy the needs of one person" (Garrison, 1996).
However, cases of extended bouts of sequential killings over periods of weeks or months with no apparent "cooling off period" or "return to normalcy" have caused some experts to suggest a hybrid category of "spree-serial killer". For example, Harold Shipman was a successful professional (a General Practitioner working for the NHS).
He was considered a pillar of the local community; he even won a professional award for a children's asthma clinic and was interviewed by Granada Television's World in Action.
Organized serial killers often plan their crimes methodically, usually abducting victims, killing them in one place and disposing of them in another.
These killers maintain a high degree of control over the crime scene and usually have a solid knowledge of forensic science that enables them to cover their tracks, such as burying the body or weighing it down and sinking it in a river.
They follow their crimes in the news media carefully and often take pride in their actions, as if it were all a grand project.
This neglect of the child leads to the lowering of their self-esteem and helps develop a fantasy world in which they are in control.
Hickey's Trauma Control Model supports how the neglect from parents can facilitate deviant behavior, especially if the child sees substance abuse in action.
