Forensics: Lamps and spectrometers used to age bruises precisely

Forensic scientists have to rely on their own subjective experience when asked to ascertain the age of contusions. Now, however, researchers in Norway have found a far more objective and precise method, using lamps and spectrometers. From the assembled data the researchers created a model for bruise progression over time which enables them to determine the age of the bruises more reliably. Bruises on children develop differently from on adults. Knowledge within this area could be particularly important in cases of suspected child abuse.
