Skin colour, veins on hands lead to conviction of paedophile
A 38-year-old UK man was given a 15-year jail sentence for filming himself raping a two-year-old girl based on video footage of his hands. In the footage from 2014, only the man's hands and private parts were visible with the face hidden. However, a detailed analysis of the suspect's skin pigment and vein patterns on hands led to his conviction.
