One of the first American profilers was FBI agent John E. Douglas, who was also instrumental in developing the behavioral science method of law enforcement. [3]The ancestor of modern profiling, R. Ressler (FBI), considered profiling as a process of identifying all the psychological characteristics of an individual, forming a general description of the personality, based on the analysis of the ...
Forensic profiling is the study of trace evidence in order to develop information which can be used by police authorities. This information can be used to identify suspects and convict them in a court of law. The term "forensic" in this context refers to "information that is used in court as evidence" (Geradts & Sommer 2006, p. 10). The traces ...
A forensic scientist who is familiar with patterns of fraudulent behaviour. After an initial analysis phase using methods of explorative data analysis the following phase is usually highly iterative. Starting with a hypothesis on how the perpetrator might have created a personal advantage the data is analyzed for supporting evidence.
Thomas Bond (1841–1901), one of the precursors of offender profiling [1]. Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator.

In forensic biology cases, the hypotheses often state that the DNA came from a particular person or the DNA came from an unknown person. [2] For example, the prosecution may hypothesize the DNA sample contains DNA from the victim and the suspect, while the defense may hypothesize that the sample contains DNA from the victim and an unknown person.
Forensic DNA analysis takes advantage of the uniqueness of an individual's DNA to answer forensic questions such as paternity/maternity testing or placing a suspect at a crime scene, e.g., in a rape investigation. Impression evidence analysis Forensic dactyloscopy – study of fingerprints.
Short tandem repeat (STR) analysis is the primary type of forensic DNA analysis performed in modern DNA laboratories. STR analysis builds upon RFLP and AmpFLP used in the past by shrinking the size of the repeat units, to 2 to 6 base pairs, and by combining multiple different loci into one PCR reaction.
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus; which is inherited from both parents, and the mitochondria; inherited maternally.
