Time since discharge of 9mm cartridges by headspace analysis, part 1: comprehensive optimisation and validation of a headspace sorptive extraction (HSSE) method

In the forensic investigation of firearms-related cases, law enforcement authorities often require evidence to link a firearm seized on a suspect to spent cartridges found at the crime scene. This generally involves mark comparisons between reference and indicial material in order to reveal common patterns between physical characteristics [1]. In some cases, however, the defence does not directly contest the source of the questioned spent cartridge, but rather its relevance, by arguing that it had been fired for legitimate reasons prior or after to the occurrence of the alleged crime [2,3].
