Abstract: Methods for linking multiple events involving firearms submit event information data and firearms information data to a system that includes a database for multiple firearms events and generate a query map that correlates data in the system database with a preselected geographical grid based upon one or more preselected matching criteria to one or more data entries for a selected event. The map is used to generate a request for a possible link analysis which may be initiated by a firearms examiner and is then performed to determine if there is a link. One or more gang database modules allow users to execute searches of a gang database and plot incidents on a geographic grid with each incident being represented by a unique icon related to a class of crime or type of incident.

The map is used to generate a request for a possible link analysis which may be initiated by a firearms examiner and is then performed to determine if there is a link. The event information data can include a case number, a geographical location data entry, a date entry, a crime type, a weapon involved and a suspect information data field based upon input from an investigating officer while the firearms information data can include a weapon data entry and a bullet data entry based upon input from a person with firearms examiner training.
