What's Criminal Profiling? Criminal profiling, or offender profiling, is the process of identifying the mindset and characteristics of an unknown criminal. Investigators examine the crime scene and the nature of the crime. The investigators attempt to determine the type of person the criminal is based on all the evidence and circumstances of the crime.
Forensic scientists can use DNA in blood, semen, skin, saliva or hair found at a crime scene to identify a matching DNA of an individual, such as a perpetrator. This process is formally termed DNA profiling, but may also be called genetic fingerprinting.
