Criminal Profiling.pptx
Psychological profiling is a forensic technique used by investigative agencies to develop a profile of the type of person likely to have committed a crime based on evidence and characteristics of the crime scene. The profile considers factors like the crime scene evidence, victimology, and forensic details to reconstruct the crime and assess whether it was organized or disorganized. This leads to developing a criminal profile with demographics, physical traits, habits, and behavioral characteristics to guide the investigation in apprehending the offender.

And case linkage uses profiling techniques to connect seemingly unrelated crimes to a single suspect or group of suspects.
