0:21:24 > 0:21:26VOICE BREAKING:
0:24:49 > 0:24:54My research has focused on looking at parts of the DNA
0:24:54 > 0:24:56that can give us information
0:24:56 > 0:24:59on physical characteristics of the individual.
0:25:00 > 0:25:04These physical characteristics are ancestry, hair colour,
0:25:04 > 0:25:07eye colour and level of pigmentation.
0:25:07 > 0:25:12One of the more straightforward traits that can be predicted
0:25:12 > 0:25:13is eye colour.
0:25:13 > 0:25:18Colonel Lago told me about the fact that they had a profile,
0:25:18 > 0:25:20it was a slightly mixed profile,
0:25:20 > 0:25:25but they had the reference of the victim and that they had no leads.
0:25:27 > 0:25:30Then, of course, Italy doesn't have a DNA database,
0:25:30 > 0:25:35so we talked about the possibility of testing some of the methods
0:25:35 > 0:25:39that I was developing for my research project,
0:25:39 > 0:25:44so I decided to focus simply on the regions
0:25:44 > 0:25:46that could help us predict the eye colour,
0:25:46 > 0:25:50because the prediction can be more precise,
0:25:50 > 0:25:54and also by looking at a lower amount of regions,
0:25:54 > 0:25:56use less of the DNA
0:25:56 > 0:25:57that I didn't have a lot of.
0:25:57 > 0:26:02The Italian driving licence, the eye colour is reported,
0:26:02 > 0:26:08so by identifying the eye colour, or the most probable eye colour,
0:26:08 > 0:26:13they were able to then tailor their investigation to that information.
