Additional information

The external temperature of the cartridge cases of 9 mm parabellum ammunition during the firing sequence was measured by a series of methods. Using a thermal imaging camera was the most successful method and showed that aluminium alloy cases reached higher temperatures than did brass cases. These times and temperature would not be sufficient to destroy any DNA residues left on the case. Measurement of the DNA of fired cartridges showed that DNA deposited on the cartridge case before firing was not affected by the temperatures reached during the firing sequence.
