Researchers from the Biomedical Research Centre at Sheffield Hallam University, however, have recently developed technology that detects condom lubricant in fingerprints. If a suspect could be tied to a crime scene by their fingerprints, and be shown to have handled a condom at that location – well, they’d have a lot more explaining to do.
