Studies into Barnum statements have also shown that the content of a profile is often so widely interpretable as to make its assertions almost meaningless.

This approach considers the pattern of documented crime scene locations in serial crimes to provide a statistical estimate of the probable residence or base of operations of an offender.
What if system read the sequence directly from DNA instead of going through big lengthy complicated and time consuming procedures avoiding Petri Dish Testing of blood samples?
In this paper, we present an overview of current research in Forensic Science. The second phase followed later and this involved studying of the crime committed by the offender. It takes exponential time to handle the DNA structure during testing and validation phase to ensure that the particular DNA belongs to right person or not.
Conclusion DNA profiling which is used in forensic evidences needed to be proficient in examining the suspect of crime. It would have been really hard to complete this project successfully without the directions of Dr.
These profiles are then used to seek out particular individuals who fit the description, or to narrow down a list of suspects by removing individuals who do not fit the description.

The deductive profiling is process oriented wherein the investigator will review the crime scene, analytical thinking and logistics to come to behavior analysis evidence.
(BEA) More emphasis is given on the study and analysis of post mortem report, forensic report and victomology. Most importantly DNA profiling is used in forensic science; used to identify who committed the crime.
