The question is why do people commit crimes? What is the real story behind the suspect's eyes? What motivates them? Is this an act just for recognition, money issues, anger issues, or some form of physiological issue? maybe just a pure and simple accident? People have been researching and questioning this for a long time. Criminologists study the causes of crime and ways to prevent it (Cause of Crime). The main question is why do people have psychological thrillers that inspire them to commit crimes? Crime began to increase around 1924-1938 (A Centennial History). Back when machine guns were being used and gangs were springing up with bosses like "Scarface" and "Bugs", it was the era of the American Gangster (A Centennial History).

Every person is unique and the way people perceive certain things or justify their actions varies. This being true, you cannot speak for an entire crowd of individuals, or in this case, criminals. Psychologists' studies can help us determine certain factors that may influence the actions of criminals. The perpetrators of the murders could have had an abnormal relationship with an individual; an abusive, neglectful or completely absent parental figure. They might also murder because they thrive on the power they feel when inflicting this on others. Thieves may steal because they really need the money, because they want materialistic things, or simply because they like being able to get what they want easily. Regardless of these factors, we can conclude that there is a certain void that people feel in their lives that they desperately need to fill; they have a dangerous need that they need
