Description

Ballistics analysis systems are automated ballistics analysis solutions that store images and information related to bullets and casings from weapons used in crimes in a computerized database to help forensic experts make appropriate identifications and support investigative or even judicial prosecution processes.
The aim is to speed up the gathering of ballistic information in police investigations and the comparison of evidence from a current investigation with previous ones and with weapons used in other (multiple) crimes.
In traditional methods of associating ballistic information, when collecting evidence from a crime scene, forensic police officers have to manually search image databases and other evidence collections to select potential candidates until they find a suspect that matches exactly. By computerizing the process through the use of integrated ballistics identification systems, these procedures of searching for and identifying potential candidate matches in past police investigations and trials are automated, thus speeding up and optimizing the analysis process.

Evidence

To date, there have been no systematic reviews for this type of program. However, a study (before/after, with an interrupted time series) on the effectiveness of the ballistics image analysis program implemented in the Ballistics Unit of the Boston Police Department (BPD) compared the system with the traditional correlation of ballistics information made by firearms examiners and forensic experts [1]. The study identified a statistically significant 6.23 times increase in the monthly number of hits generated (association of crimes with firearms).
