NIBIN and Crime Scene Reconstruction Quiz 2

National Integrated Ballistics Information Network.

ATF and FBI combined systems in 1999. ATF and FBI work together to enter image acquisition, capturing, and comparing information to IBIS.

Integrated Ballistics Identification System. Collects images of unique microscopic markings found on fired bullets and cartridge cases.

Allow federal, state, and local law enforcement agencies to acquire images of fired ammunition components and compare them with other local agencies.

Correlated over a network compiling similar markings based on shades of black/white/gray and other viable characteristics required by the system.

If a high-confidence match (highly similar) or image hit is found, then the image will then be further examined by a firearms examiner.

Technology provides agencies the capability to search investigative information across jurisdictional boundaries outside their regions.

Coordinate entry of suitable ballistic information entered by Federal, State, and local agencies to identify all possible links in violent shootings. Refer leads to others in order to solve, prevent, and reduce firearms-related violent crimes.

Found on every continent with a forensic laboratory (28 countries).

Forensics Technology Incorporated. Hold offices all around the world.

Originally divided into 12 regions, now there are 16. 222 sites nationwide. Images sent to Data Acquisition Station (DAS) within each region. We are region 2.

Accepts bullets, fragments, shotshells, and cartridge cases.

Headstamp. Breech face markings. Extractor mark. Ejector mark. Firing pin impression. Drag mark.

Collect, store and compare, analyze and report.

Collects images. Electronic signature extracted from each image and stored in database. System automatically compares signatures in attempt to find match. System ranks most likely matches for experts to examine further.

Helps identify patterns and trends to assist law enforcement.

Only does cartridge cases. Automation reduces operator variability and ensures consistent image quality. Hands-off operation allows for multitasking.

Only does bullets. 360 degree imaging of lands and grooves. Test fired and damaged bullets. Image quality, reduced operator time, allows for multitasking.

Analysis of 2D/3D comparison results of bullets and cartridge cases. Quantitative evaluation based on the topographical markings of 3D surface of bullet. Generates reports and has multiviewer.

General Rifling Characteristics file. Maintained by FBI. Investigative aid, not all inclusive. Errors exist due to incorrect input of data by people.

Collection of known samples of ammunition. May contain samples of projectiles, propellant powder, primers, cartridge cases or other components.

A tool for examiners to link consistency amongst manufacturers. Document known characteristics exhibited on ammunition that has been examined in the lab.

Collection of known firearms. May contain exemplar firearms, parts, historical firearms, or ones specifically utilized by the agency.

Exists as a reference for examiners to utilize gun parts, learn functioning, test fire, identify, instruct, and link similarities between manufacturers. Also serial number characteristic identification.
