Criminal Profiling: An Introduction to Behavioral Evidence Analysis

Now in its fourth edition, Criminal Profiling is an established text centered on the deductive profiling method developed by the author. Deductive profiling is different from other forms of profiling in that it does not involve averaged, statistical profiles. Instead it focuses on criminal profiling as an investigative process, solving real crime through an honest understanding of the nature and behavior of criminals. It approaches each criminal incident as its own universe of behaviors and relationships. Throughout the text, the author illustrates the most crucial tenet that any good criminal profiler should adhere to: the enthusiastic desire to investigate and examine the facts. Criminal Profiling is an ideal companion for students and professionals alike, including investigators, forensic scientists, criminologists, mental health professionals, and attorneys. Readers will use it as a comprehensive reference text, a handbook for evaluating physical evidence, a tool to bring new perspectives to cold cases, and as an aid in preparing for criminal trials.

In an extortion case, the offender sent a message to the victim from a Web-based e-mail account. The Internet protocol (IP) address contained in the e-mail header showed that the message was sent from a computer located in an Internet café, but investigators were unable to determine who was using the computer at the time. Believing that the offender may have checked the Web-based e-mail account for responses to his message, investigators obtained all records relating to that account from the Internet service provider. These records indicated that the offender had indeed connected to the e-mail account from his home computer.
