Forensic and the MODUS OPERANDI and Offender Signature

First of all, all criminals have a MODUS OPERANDI. The MODUS OPERANDI consists of different techniques, habits and peculiarities in behavior. They are performed with three objectives, (Complete the crime, affect escape, and avoid capture or investigation.) Serial offenders modify and perfect their MO as they become more adept at what they do. Where as; the OFFENDER SIGNATURE can be broken down into two separate interdependent halves: signature aspect and signature behavior. Signature aspect defines the theme or motive of an offense, and can include motivational categories such as profit, anger, retaliation, assertiveness, and sadism, (Turvey, 2002). Signature behaviors, on the other hand, are committed to satisfy the emotional and psychological needs of the offender and usually define the theme of a crime.
