Fingerprints could soon help police narrow down their list of suspects by giving clues about the lifestyle of whoever left the prints at the scene of a crime.
Researchers in the UK are uncovering the ways fingerprints are changed by age, smoking, drug use and even some personal grooming products.
The work also promises to help obtain good quality copies of prints that have gone unnoticed for days or weeks.
