Serial Killers

Serial killers are individuals who commit a series of murders over an extended period of time, typically with a cooling-off period between each crime. They often share certain characteristics and patterns, allowing law enforcement to potentially create a profile to aid in their identification and capture.


Developing a profile of a serial killer involves analyzing various aspects of their crimes and behavior.

The modus operandi, or MO, refers to the specific methods a serial killer employs to carry out their crimes. This can include their preferred victim selection criteria, choice of location, and specific actions taken during and after the murders. Analyzing the MO helps investigators identify similarities between different cases and potentially connect them to a single perpetrator.


While the modus operandi focuses on the practical aspects of the crime, the signature represents the unique characteristics or rituals that a serial killer incorporates into their murders. This can include specific behaviors, mutilations, or objects left behind at the crime scene. Understanding the signature can provide further insights into the psychological motivations and fantasies of the killer.

Unsub (Unknown Subject)

The term “unsub” is often used in criminal investigations to refer to an unknown subject or suspect. In the context of serial killers, it is frequently used to describe the individual responsible for a series of unsolved murders. Law enforcement agencies work tirelessly to uncover clues and gather evidence that will lead to the identification and capture of the unsub.
