Introducing the Evofinder Automated Ballistics Identification system

The Evofinder® Automated Ballistics Identification system (BIS), produced by ScannBi Technology, is a scanning device that captures 2D & 3D digital images of bullets and cartridge cases to store in a database for the purpose of comparison and matching.

Main Features of the Evofinder® BIS:

  • To scan, process and store high quality 2D and 3D digital images of a full or fragmented surface of a bullet, including strongly deformed ones, and any bottom or side surface of cartridge-casing.
  • To create a database of spent bullets and cartridge-case images and hold in a single information network.
  • To carry out automatic identification of the object under examination among the objects in the database and to provide experts with a “hit list” of similar objects.
  • To view a scanned object’s surface on monitor and carry out manual or auto-focusing, change the direction of light, etc., for comparison of images.
  • To recall previously saved images in the given scale, move the images independently and align images for the sake of manual comparison identification.
  • To print images and reports to be represented in court.

Evofinder® technology includes multi-sided illumination, 2-sided separate lighting for bullets, and 4-sided separate lighting for cartridge-cases.

The Evofinder® is easy to use, with an adjustable universal detachable cassette to hold bullets and cartridge cases.  Once object has been loaded, the cassette is inserted into the Evofinder for scanning, the scanning process takes approximately 2-3 minutes.

Same Gun, Different Scene: The Process of Matching Firearms Evidence Samples through the Use of Automated Ballistic Identification Systems

Forensic laboratories are always trying to find faster ways to process evidence in the efforts to battle crime, including the examination and comparison of bullets and cartridge cases for support of police investigation and criminal prosecution.

With the development of technology in the forensic lab, one of the newer technologies in identifying links between separate crime scenes is the introduction of the automated ballistic identification systems.  These are systems which take digital images of evidence samples and utilize algorithms to locate possible matches between evidence samples at completely separate crime scene locations, providing possible links to help with criminal investigations.

Automated ballistic identification systems are designed to scan bullets and cartridge cases, adding them to a database, and then be able to develop correlated searches for other samples in the database which could match the current test sample.  These possible matches are referred to as unconfirmed hits until they have been directly compared by a trained firearms examiner to make a determination about the samples.

National Integrated Ballistic Information Network (NIBIN)

NIBIN is a database of breech face images of cartridges that have been scanned by automated ballistic identification workstations.  This database is maintained by the ATF (US Bureau of Alcohol, Tobacco, Firearms & Explosives).  There are over 150 NIBIN sites used by federal, state, and local law enforcement throughout the United States.

Automated Ballistics Identification Scanning Systems

Automated Ballistics Identification Scanning Systems are scanning devices which generates digital images of bullets and cartridge cases for examination, comparison, and correlative searches within existing databases, like NIBIN.  These workstations can execute matching algorithms to find unconfirmed hits which are presented in an order of the likeliness of a match.  A hit is not a proven match between samples.

Confirming Matched Ballistics Evidence

A comparison microscope is used to compare the actual (physical) samples of the unconfirmed hit, obtained from police evidence files, to allow the examiner to make a determination if the samples match (or identify that there is insufficient information to make a determination).  This result can then help police using these tools to determine if there are multiple crime scenes at which the same firearm may have been used, further aiding in their investigations and providing a link between the evidence samples that can also be used in court cases.  Leeds’ firearm comparison microscopes are utilized as part of both examinations and confirmations made by examiners at numerous agencies sites across the United States.

Leeds LCF3 Firearms & Tool Marks Comparison Microscope

Leeds LCF3 Firearms & Tool Marks Comparison Microscope

The LCF3 firearms and tool marks comparison microscope’s design incorporates examiner feedback, focusing on image resolution, sample handling, ergonomics, and versatility. These design concepts provide examiners with features that can increase the rate at which examiners complete forensic examinations. This allows for faster actionable results such as helping move through case backlog or providing quicker hit confirmations from automated ballistics identification systems like Evofinder®.

As laboratories take advantage of the advances in technology and organizational structuring around the 48-hour confirmation response times from submission to confirmation, the importance of high-performance, workflow-oriented and reliable comparison systems become more pronounced (AFT’s video of NIBIN and Leeds’ LCF microscope working to solve violent crime in Jefferson Parish, LA).

Putting Leeds Forensic Products to the Test

As a manufacturer of comparison microscopes and imaging systems for forensic and education laboratories in the United States and around the world, Leeds products often follow a similar path from start to finish:

Design – Manufacture – Install

In most situations, our products are purchased by forensic labs, residing in contained office buildings or controlled environment laboratory spaces.  In addition, we often revisit our customers, offering annual service plans to maintain these powerful microscopes and imaging systems.

Recently, we were surprised (not once, but twice) by two unique situations:

The LSV2 at a forensic conference in Saudi Arabia

The LSV2 at a forensic conference in Saudi Arabia

1)  In November of 2015, Leeds attended a forensic conference in Riyadh, Saudi Arabia, demonstrating our LSV2 imaging system to attendees interested in using the system to identify bodily fluids on forensic evidence.  Upon arrival, our Leeds staff member discovered the booth space was outdoors, surrounded by desert heat, winds, and sand.  Our LSV2 demonstration system withstood the elements for the entire duration of the conference with no issues.  Even upon returning to our shipping dock, we found only minor remnants of sand particles.

2)  In the fall of 2015, we received an email from our customer in the middle east, along with an interesting photograph of our firearms comparison microscope.  The microscope had been donated to Afghanistan and was currently residing in the Kabul laboratory.  Interestingly enough, in order to get the microscope to this laboratory, it had

to be transported by truck through the mountains from Bagram to Kabul over rough terrain and unpaved roads.  Our customer commented, “I personally used that scope…and considering the abuse it has faced [during transport] your product has performed exceptionally well.  I credit much of [the microscopes’] durability to the fact that the LEEDS microscope was designed for easy maintenance”.

We work hard to provide our customers with the most durable products for their forensic disciplines.  These two examples prove just how tested our equipment is.  Interested in learning more?  Please call 1.800.444.5333 or contact Leeds.
