The U.S. holds 67.58% of all serial killers (Aamodt). The FBI hopes to catch all of them with the process of behavioral analysis. Behavioral analysis was introduced by Harold Teten in 1969. He had been recruited by the FBI and became a lecturer for criminal psychology. He taught the four hour lecture in one session at a police academy in New York and received full praise for the class. Therefore, Teten went on to teach the lecture to a criminal psychology class, but split it into four days of class. By day three, students were asking about unsolved cases. One student even interviewed a suspect to an open case who confessed to the crimes and was arrested. The FBI saw the importance of this behavioral analysis (later called criminal profiling)

Studies of serial killers have shown similarities in childhood that may be a foreshadow to the future. “Neglect and abuse in childhood have been shown to contribute to an increased risk of future violence” (Johns). Similarities between the criminals who commit the same crime make determining the background of the crime and predicting the outcomes simpler. Specifically, agents analyze the crime scene and find the motives of the killer through the way the crime scene was left. To illustrate, the way serial killers kill show what causes their anger to kill. “Sexually-based is a motivation driven by the sexual needs/desires of the offender. There may or may not be overt sexual contact reflected in the crime scene” (Johns). “Anger is a motivation in which an offender displays rage or hostility towards a certain subgroup of the population or with society as a whole” (Johns). This is usually shown through extreme violence shown in the scene and the victim’s body. The generalities in the similarities allow for an accurate prediction of the outcome by studying the arrests of the killers. The similarites in those outcomes will more than likely appear in the arrests of others. This type of analysis has proven successful by the fact it has been used since the mid
