The inventor of a revolutionary new forensic fingerprinting technique claims criminals who eat processed foods are more likely to be discovered by police through their fingerprint sweat corroding metal.
Dr John Bond, a researcher at the University of Leicester and scientific support officer at Northamptonshire Police, said processed food fans are more likely to leave tell-tale signs at a crime scene…Dr Bond said sweaty fingerprint marks made more of a corrosive impression on metal if they had a high salt content.
And he revealed he was currently in early talks with colleagues at the University of Leicester to assess whether a sweat mark left at a crime scene could be analysed to reveal a ‘sweat profile’ ie more about the type of person who left the mark.
Dr Bond…has developed a method that enables scientists to ‘visualise fingerprints’ even after the print itself has been removed. He and colleagues conducted a study into the way fingerprints can corrode metal surfaces. The technique can enhance – after firing– a fingerprint that has been deposited on a small calibre metal cartridge case before it is fired.
RTFA – there are some interesting avenues for forensic research suggested by Dr. Bond’s work.
