We received a section of an individual’s skull which showed the impressions of some form of instrument. The micro-CT displayed these impressions in great detail, revealing two distinct shapes. These could be matched with a hammer and a spanner that were found at the scene, proving that both tools had been used.
The skull section was 3D printed and shown to the jury during trial to visualise the injuries. This was accompanied by Professor Williams giving expert witness testimony regarding the scanning and 3D printing processes to validate the evidence.
