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. Speaking
before a conference on forensic science at the University of
Leicester, 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, from Northamptonshire Police Scientific Support Unit is an
Honorary Research Fellow at the University of Leicester's
Forensic Research Centre. He has developed a method
