Compiled jointly by experts from the Public Security Administration Bureau of the Ministry of Public Security and the Ordnance Equipment Research Institute of China South Industries Group over a period of ten years, this system includes CD-ROM software and supporting books "Illustrated Dictionary of Firearms Identification". It is the largest-scale and most comprehensive firearms and ammunition identification tool in China, covering core functions such as firearms identification, ballistic analysis, trace comparison, and forensic report automatic generation. It provides comprehensive and accurate technical support for criminal investigation and forensic identification of firearms-related cases, greatly improving the efficiency of handling firearms cases and the standardization of identification, and is an indispensable equipment for investigating firearms-related cases.
Core Application Scenarios and Forensic Identification Value
1. On-site Investigation and Physical Evidence Identification of Firearms-Related Cases: For shell casings and warheads left at the crime scene, it can quickly compare the base marks of shell casings and warhead characteristics from countries around the world in the database, accurately identify the firearm model, matching ammunition type and place of production. It provides direct evidence for case characterization and locking the source of firearms, solving the pain points of difficult and inefficient on-site physical evidence identification.
2. Ballistic Analysis and Shooting Scene Reconstruction: Based on on-site investigation data, it can automatically calculate ballistic trajectories, infer shooting points, analyze shooting distance and angle, output complete ballistic tables, assist in reconstructing the crime scene, provide scientific data support for case analysis and investigative experiments, and help forensic identification accurately determine shooting facts.
3. Trace Comparison and Linked Case Investigation: It can splice, compare and measure the rifling scratches on shell casings and warheads, realize rapid comparison between on-site physical evidence and database samples, establish inspection basis for linked cases, help investigators connect a series of firearms-related cases, and narrow the scope of investigation.
4. Standardized Generation of Forensic Reports: Equipped with a professional automatic forensic report generation system, it supports image comparison, feature labeling, 3D visualization and dynamic comparison, and can automatically generate standardized forensic reports. It meets the compliance requirements of forensic identification documents, reduces errors caused by manual writing, and improves identification efficiency.
Typical Criminal Investigation Application Cases
- Investigation of Series of Firearms-Related Robbery Cases: Through the shell casings left at the scene, the system compared the base marks and rifling traces in the database, quickly identified the firearm model, linked 3 cross-regional robbery cases, locked the same crime firearm, provided core identification basis for linked case investigation, and successfully arrested the suspect.
- Reconstruction of Firearms-Related Homicide Scene: Using the on-site warhead and shell casing data, the system inferred the shooting point and shooting angle, reconstructed the position of personnel and the shooting process at the time of the incident, and provided scientific forensic identification support for case characterization and liability determination.
- Physical Evidence Identification of Illegal Firearms Possession Cases: For the seized suspicious firearms and ammunition, the system quickly identified the firearm type, place of production and matching ammunition type through the database, completed trace comparison and identification, and automatically generated a standardized forensic report, providing compliant evidence for case prosecution and trial.
