Procedure in identifying fingernail imprint in human skin survives appellate review

A case of first impression involving the identification of the person whose fingernail left an imprint on the neck of a child murder victim has survived appeal to the Pennsylvania Superior Court. The appeals court, in an opinion which includes a number of incongruous features, approved the trial court's admission of scientific testimony matching an accused's fingernail to the impression left in the child's neck, apparently during his being manually strangled.
