Technological advancements, including high-powered computers and sophisticated forensic machinery, have a dramatic influence on law enforcement. Criminal investigations often are solved by analyzing one strand of DNA or a smudged fingerprint. Advancements in technology also help in profiling. For example, criminal profilers use software to gather information about the locations of the killings to create a geographical profile of the serial murderer. Other computer programs help to identify all of the victims who were murdered in the same fashion, even if they cross jurisdictional boundaries. Police agencies across the United States can enter information about unsolved murders, including specific details of a victim’s demise. Investigators can review these details to determine whether certain victims are linked to the same serial murderer. These technological discoveries continue to evolve and likely will increase the accuracy and effectiveness of criminal profiling in the future.
