The Skin as a Repository and Masker of Evidence

The role of the skin as a repository and masker of evidence is evaluated. Skin examination and testing are very important in the (a) identification of victims and suspects (for example, by fingerprints, lip prints, and fingernail marks), (b) recognition of patterns and shape of injurious energy impacts (for instance, recognition of type of injury and particular weapon), and (c) recovery of embedded evidence (for example, glass, wood, powder, explosives, and paint). It is also important to realize that the skin may conceal evidence by masking significant and/or lethal internal injuries.
