Crime Gun Intelligence and Gun Enforcement



Crime, Guns & NIBIN: Collect, compare the casings, connect the dots

The unique markings left on spent bullets and cartridge casings can be the firearm equivalent of pocket trash: of great value to a law enforcement investigator, if the information has been properly collected and processed and is readily available. Information that might seem of little value to one agency can be a critical factor to the success of another agency's investigation. Read more.


Crime Gun Intelligence and Gun Enforcement

Crime Gun Intelligence programs including NIBIN (National Integrated Ballistic Information Network) and e Trace can provide actionable intelligence for cases involving the use of firearms. The NIBIN program, adminstered by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) involves the entry and comparison of computer images taken of fired cartridge casings left as crime scenes, as well as those from seized firearms that are test-fired by law enforcement personnel. Following analysis of possible matches, crimes involving the use of the same firearm, previously not known to investigators, can be linked together providing valuable intelligence and leads. Firearm tracing through eTrace, also administered by ATF, involves the systematic tracking of recovered firarm from its manufacturer or importer and subsequent introduction into the distribution chain (wholesaler/retailer) to the first retail purchase. Tracing information can be used to link a suspect to a firearm in a criminal investigation and to identify potential traffickers. When implemented together in a timely manner, these crime gun intelligence programs can provide critical information to help investigators and identify offenders.  Click on the link above for additional information from ATF regarding firearm tracing.


To utilize these crime gun intelligence programs to their fullest potential, and to help generate timely leads for investigators, the Phoenix Police Department Crime Gun Intelligence Squad has developed the INTEL program (Immediate NIBIN and Tracing Equals Leads) to ensure the timely submission of evidence into NIBIN - with a goal of providing leads within 24 - 48 hours of an incident. In partnership with the Phoenix Police Department Crime Lab and ATF, the Crime Gun Intelligence Squad works closely with investigative details throughout the Department, as well as the Property Management Bureau, to provide timely crime gun intelligence to detectives. This squad, assigned to the Violent Crimes Bureau Assaults Unit, is supervised  by a sergeant and is comprised of civilian, sworn and volunteer personnel.

Due to a limited number of NIBIN sites in Arizona, the Phoenix Metro NIBIN Program was launched by the Phoenix Police Department (PPD) in July 2010 in partnership with ATF. Personnel from law enforcement agencies throughout Arizona receiving the requisite training and certification are welcome, and encouraged, to enter their ballistic evidence at the Phoenix Police Department NIBIN site utilizing one of the three IBIS BRASSTRAX entry and four MATCHPOINT analysis stations. To date, 22 agencies have participated in this program with more than 29,000 entries having been completed at the PPD NIBIN site representing 36 different law enforcement agencies. Hundreds of hits have been identified during this time, with many of these hits involving shootings and other firearm-related crimes that have occurred in different jurisidictions. The case linkages and intelligence provided would not have been possible without this regional program.
