Ballistic fingerprinting – forensic techniques that rely on marks that firearms leave on bullets to match a bullet to the gun it was fired with. [ 6 ] 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 ...
After test firing the guns, Goddard proved that the weapons were those used to kill the members of the North Side Gang, absolving the Chicago police department of all involvement. [12] The successful use of Goddard's technique resulted in the solidification of his place as the father of forensic firearm examination.
The two basic conceptual foundations of forensic identification are that everyone is individualized and unique. [2] This individualization belief was invented by a police records clerk, Alphonse Bertillon, based on the idea that "nature never repeats," originating from the father of social statistics, Lambert Adolphe Jacques Quetelet.
Comparative forensics is the application of visual comparison techniques to verify similarity of physical evidence. This includes fingerprint analysis, toolmark analysis, and ballistic analysis. Computational forensics concerns the development of algorithms and software to assist forensic examination.
Automated Firearms Identification has its roots in the United States, the country with the highest per capita firearms ownership. [1] [2] In 1993, the Federal Bureau of Investigation commissioned Mnemonics Systems Inc. to develop Drugfire, which enabled law enforcement agencies to capture images of cartridge casings into computers, and automate the process of comparing a suspect cartridge ...
While some groups have advocated laws requiring all firearms sold be test-fired and registered in such a system, success has been mixed. In 2005, a Maryland State Police report recommended a law requiring all handguns sold in the state be registered in their IBIS system be repealed, as at the cost of $2.5 million the system had not produced ...

When a firearm or a bullet or cartridge case are recovered from a crime scene, forensic examiners compare the ballistic fingerprint of the recovered bullet or cartridge case with the ballistic fingerprint of a second bullet or cartridge case test-fired from the recovered firearm. If the ballistic fingerprint on the test-fired bullet or ...
