Fingerprints betray cocaine users in new forensic technique

The University of Surrey in cooperation with the Dutch Forensic Institute have developed a new method to determine whether someone used cocaine that can give results with extreme accuracy. Fingerprints treated with a methanol solution are then analyzed by a mass spectrometer, and can positively identify a cocaine user, Sky News reported. "If anyone says that the drugs were placed in their bag and they knew nothing, he has more to explain if we can prove that he indeed touched cocaine," said Marcel de Puit, a fingerprints expert at the NFI. De Puit also pointed out that the new technique could allow investigators to determine if a suspect was under the influence of drugs when they committed a crime.
