When conducting a seminar about crime scene forensic investigation, look for or hire a keynote speaker who works as a forensic investigator in a police department. Specifically hire a person with years of experience in their field in order for them to produce better and in depth discussions regarding the use of forensic investigation in a crime scene. These investigators will discuss and tackle topics on how to use certain forensic evidence and analysis to catch the specific culprit of the crime. Listed below are some of the topics a keynote speaker for a forensic seminar will tackle in their discussion.
Collecting evidence
One major topic a keynote speaker will tackle about in a forensic seminar is about properly gathering evidence. There are some crime scene personnel who mishandle and does not properly gather or obtain the evidence from the scene of the crime. First is to take a picture of the evidence before it is bagged and tagged as to where it was found and what kinds of analysis should be run in order to identify them. Next is to take a picture of everything in the area or room should an investigator move certain things in order to reach evidence. These are just standard procedures an investigator should always remember.

Fingerprinting
An investigator should gather fingerprints in the area or near the area of the scene of the crime. They need to look into places where a suspect might have touched or passed by and gather fingerprints in that area. These prints are then cataloged and sent to a laboratory for analysis and identification. It is crucial for investigators to immediately know whom those prints belong to in order to question those individuals.
Ballistics and gun powder residue tests
These tests are mostly done when investigators have in custody a certain perpetrator who may have fired a gun recently. Gun powder residue test are done with the consent of the person in question.
In the event the investigators find a gun that was used in a crime scene, then this is where they perform ballistic tests on it. If the gun has been recently fired or if the bullet of the gun matches the one they have gathered in the crime scene. If a suspect is caught with a gun they also perform the same gun powder residue test on the perpetrator and the ballistic tests on the gun.
Gathering D.N.A
One of the most important evidence an investigator finds at a crimes scene is a foreign D.N.A. that might belong to the perpetrator of the crime. After gathering the D.N.A. evidence, it is then sent to a lab for analysis and comparison. These keynote speakers will explain how a sample will be analyzed and will go through their criminal database in order to find a match from any known perpetrators that may have already been recorded in the database. After matching the sample to a suspect then they are brought in for questioning about the crime.
