Genetic profiling from 9mm fired cartridge cases over 30 days

Fired cartridge cases are common materials found at crime scenes and, for the most part, are used for Forensic Ballistics analysis. We aimed to evaluate the feasibility of recovering DNA profiles from 9mm cartridge cases over 30 days. Therefore, 27 fired cartridge cases were manipulated by three volunteers in total and analyzed after three-time intervals: 3, 8, and 30 days. Volunteers were asked to handle the ammunition as they would daily. However, they were not encouraged to hold and manipulate the ammunitions extensively, as this procedure does not represent a real-life situation.
