Introduction
Despite the various reasons that different individuals might have for engaging in crime and criminal activities, there is no justification for unlawful behavior.
There are some criminal activities that are considered to be of greater magnitude when compared to others. For instance, pick pocketing, vandalism and defamation cannot be placed on the same pedestal such as rape, human trafficking and murder. The legal system in America has a long history with some serious crimes such as the criminal cases that involve many people or the cases that evoke a lot of public interest.
Some of these cases that spark off public interest include serial killer cases. This paper seeks to examine the case of the Zodiac Killer by looking into his case profile and trying to develop a forensic psychology insight into his case.
The paper will also attempt to analyze what was unique with the Zodiac Killer.
A serial killer can be described as an individual who commits more than three murders for the purpose of gratifying unusual or abnormal psychological needs.
Also, a serial killer can be a person who commits a series of murders, one after another, in a similar manner in different locations (Cahill, 2014).
Serial killers usually murder as many people as possible over a period of time but often take breaks of unspecified time to cool off before resuming their cycle.
Different serial killers are driven by different forces to commit their crimes. Some of the most common motivations for serial killers include;
• Power and Control -The drive of some serial killers is to be in control over their victims through having the power to decide how to torment them and also how to murder them.
• Visionary - Some killers are driven to commit their crimes. They claim that a higher power drives them to commit numerous murders and that they are unable to resist the urge. Visionary serial killers claim that the higher power compels them to murder. They view their actions as a way of ridding the world of unworthy people.
• Thrill - There are killers who thrive on the adrenalin rush they experience when they kill an individual.
Some also love to experience the fear and terror that their victims show when they realize they are about to die (Cahill, 2014)
