Firearms and Toolmarks
The Integrated Ballistics Identification System (IBIS) is used for the acquisition, storage and comparison of digital images from projectiles and/or cartridge/shotshell cases. The system is a screening tool that enables the laboratory to identify local, national and international linkages that may exist amongst firearms cases submitted for examination. Through the use of computers and a modified microscope, an operator can compare previously recorded images to new evidence received.
Firearms, projectiles, and cartridge/shotshell cases can be examined for IBIS upload. Images of projectiles and/or cartridge/shotshell cases are digitally captured, and uploaded for comparison. The uploaded images will be electronically compared to those images stored in the Canadian Integrated Ballistics Identification Network (CIBIN).
Those images could also be compared to the National Integrated Ballistic Information Network (NIBIN) database in the United States of America where information indicates that the firearm may have originated or passed through the USA. The submission form must include the reason for the search (e.g. firearm was stolen or purchased in the USA) and the specific state(s) that the agency would like to search.
Where linkages to other cases are identified and confirmed, a report is issued to notify the agencies involved*.
*Note: All identification/associations are made within the limits of practical certainty.
If a firearm, projectile or cartridge/shotshell case is submitted for upload to IBIS, then the examination may include the following:
- Examining the projectile and/or cartridge/shotshell case to determine suitability for acquisition
- Capturing and uploading digital images of the projectiles and/or cartridge/shotshell cases
- Correlating the uploaded images with those in the CIBIN database, and where applicable, the NIBIN database
- Examining the projectiles and cartridge/shotshell cases microscopically and comparing them to each other using a comparison microscope
As IBIS is a screening tool, potential linkages identified by the system must be reviewed and microscopically examined to confirm the association.
There are three possible results from an IBIS acquisition and comparison:
- A submitted item is associated with items held in the CIBIN and/or NIBIN database(s). Investigators from the case(s) involved will be notified through a report detailing the linkages that have been identified.
- At the time of capture and upload, there were no items held in the searched database(s) with which the submitted item could be identified. This means that an association of common source through physical characteristics and markings cannot be drawn between the submitted items and items in the searched database(s).
- The item was not acquired. Occasionally, technical limitations associated with the appearance or absence of microscopic, individual characteristics of an item may preclude its acquisition into IBIS. A manual comparison will be conducted in this event, as per unit procedures.
CIBIN: a national network that integrates all IBIS Sites in Canada and is administered by the Royal Canadian Mounted Police (RCMP).
NIBIN: a national network that integrates all IBIS Sites in the United States of America and is administered by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
Firearms/Toolmark Identification: is an empirical science that relies on objective observations and a subjective interpretation of microscopic marks of value.
Practical Certainty: Since it is not possible to collect and examine samples of all firearms, it is not possible to make an identification with absolute certainty. However all scientific research and testing to date and the continuous inability to disprove the principles of toolmark analysis have demonstrated that firearms produce unique, identifiable characteristics which allow examiners to reliably make identifications.
