Signature

In sum, signature is a combination of behaviors, emotions, and thoughts.  The signature is sometimes called a "trademark" or "calling card" and reflects a compulsion on the part of criminals to go beyond just committing the crime to "express themselves" in some way that reflects their personality. Douglas & Olshaker (1998:90) define it as "something the offender has to do to fulfill himself emotionally ... it is not needed to successfully accomplish a crime, but it is the reason he undertakes the particular crime in the first place."  Signatures usually put the offender at great risk because they must stay at the crime scene longer, so ordinary signature is often hard to detect.  At other times, it's obvious, such as when an offender goes to the trouble of leaving a Bible at the scene of the crime.
