Crime Lab
A crime laboratory, often shortened to crime lab, is a scientific laboratory, using primarily forensic science for the purpose of examining evidence from criminal cases. Lab personnel A typical crime lab has two sets of personnel: *Field analysts – investigators that go to crime scenes, collect evidence, and process the scene. Job titles include: **Forensic evidence technician **Crime scene investigator **Scenes of crime officer (SOCO) *Laboratory analysts – scientists or other personnel who run tests on the evidence once it is brought to the lab (i.e., DNA tests, or bullet striations). Job titles include: **Forensic Technician (performs support functions such as making reagents) **Forensic Scientist/Criminalist (performs scientific analyses on evidence) **Fingerprint Analyst **Forensic Photographer **Forensic Document Examiner **Forensic Entomologist Crime labs United States In the United States, crime labs may be publicly or privately operated, although private labo ...

Forensic Science
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals.

Ballistic Fingerprinting
Forensic firearm examination is the forensic process of examining the characteristics of firearms or bullets left behind at a crime scene. Specialists in this field try to link bullets to weapons and weapons to individuals. They can raise and record obliterated serial numbers in an attempt to find the registered owner of a weapon and look for fingerprints on a weapon and cartridges. By examining unique striations impressed into a bullet from the barrel of a gun, expended ammunition can be linked back to a specific weapon. These striations are due to the rifling inside the barrels of firearms. Rifling spins the bullet when it is fired out of the barrel to improve precision. Although bullet striations are individualized unique evidence, microscopic striations in the barrel of the weapon are subject to change slightly, after each round that is fired. For this reason, forensic ballistics examiners may not fire more than five shots from a weapon found at a scene. Known exemplars taken ...
