Another duty of our Examiners is to restore obliterated serial numbers on firearms or other items. After preparing the surface, the Examiner applies different chemical solutions to restore the numbers.
After a case is worked, an Examiner will write a detailed report concerning scientific findings related to Firearm and Toolmark analysis. Then, upon request, the Examiner will testify in criminal proceedings based upon these findings as an expert witness in the area of Forensic Firearm and Toolmark examinations.
The National Integrated Ballistic Information Network (NIBIN)/ Integrated Ballistics Identification System (IBIS) is a national database of digital images of ballistic evidence found at crime scenes or test-fired from confiscated weapons. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) manages the system.
Examiners have access to the national database to capture and compare ballistic evidence to aid in solving and preventing violent crimes involving firearms. Specimens entered into NIBIN/IBIS are scored then searched and correlated with similarly scored specimens previously entered by our laboratory and other agencies. Automated searches are regional (entries from the St. Louis Metropolitan Area, Missouri State Highway Patrol and Illinois State Police – Belleville Laboratory), but manual searches of any participating agency in the world are possible. Although each specimen is actively searched only once, it is forever retained in the database and searched with each new submission of the same caliber. Our Examiners have discovered hundreds of case relationships using NIBIN/IBIS
