ABSTRACT
Cartridge cases are crucial physical evidence in gun-related crimes. The successful identification of the touch DNA on cartridge cases can help to screen the suspects and reconstruct the gun-related crime scene. With the improvement of DNA extraction methods and the sensitivity of amplification kit, forensic examiners are expected to obtain more valuable information by testing the touch DNA on cartridge cases. In practical cases, the touch DNA detection on cartridge cases often encounters with low DNA content degradation, mixing and the gunshot residual interference, which brings more challenges to DNA examination and identification. This article reviews forensic research of touch DNA on the cartridge cases from the aspects of factors affecting touch DNA on cartridge cases, advances in the extraction and amplification methods, and the practical applications in order to provide reference for forensic identification of touch DNA on the cartridge cases in real cases.
