Fingerprint molecule tech to be used in UK courts

Mass spectrometry technology that finds substances and other details in fingerprints, developed by UK researchers, could soon be admissible in court.

The system is being piloted by Sheffield Hallam University and West Yorkshire Police.

Dr Simona Francese told the BBC this week that the technology had been used to detect blood in a 30-year-old print, meaning it could be used in cold case reviews.

"I would want to see this technology in high-profile cases such as murder or rape. It's very sophisticated, it's expensive but it's worthwhile," she added.

The analytical technique is used to find traces of substances on or within the ridges of the fingerprint.

It works by vaporising the sample and then firing it through an electric and magnetic field inside a vacuum.
