- Something the offender does at the crime or takes away from the crime that is unique/distinct and consistent-- reflects psychological need (have to be psychologically fulfilled, they leave their mark) - More personalized than MO, goes beyond what is needed to accomplish the crime. includes 1.some aspect of sexual fantasy 2. toys with the investigators |
|
|
2. Modus Operandi |
