A deceptive case of gunshot entry wounds -- beware of frangible bullets.

In December 2003, two young men decided to go shooting in the countryside near Montpellier, France. One accidentally shot the other. Upon crime scene examination and autopsy of the victim experts observed, at the right thorax, two round wounds, distanced 5mm from each other, presenting typical characteristics of entry wounds of bullets shot from a distance. Because of the presence of two clear cut round wounds, the Procurator suspected voluntary homicide. However, thanks to the balistics expertise, the authors concluded that all fragments belonged to a unique projectile, 22 Short caliber (Remington cartouche) of the frangible type. The barrel of the rifle infact presented an imperfection where the screw was fixed on the frontsite. The screw had obviously been changed, and the new screw was longer and therefore extended into the barrel, causing a small obstacle to the bullet when exiting the barrel. Shooting tests were performed, allowing the authors to conclude that a single bullet had fragmented before entering the body into two fragments. This lead the Procurator to consider the lesions consistent with an accident.

Forensic anthropology: developments of a classical discipline in the new millennium.

The present brief review is a survey of the role of forensic anthropology (FA) in the new millennium. After an introduction which deals with the expanding definition of the discipline and the issue of professionality and training, the author approaches the role and novel developments of the field, with particular reference to the past 5 years. Such developments are discussed in a sectorial manner, distinguishing the role of research in the areas of forensic anthropology which deal with human remains and those that deal with the living. As regards the "human remains" domain, advances and stalls still present in the fields of species and postmortem interval determination, sexing, aging and attribution of ancestry are stressed. The need for standards in facial reconstruction and positive identification by bone morphology are underlined, as well as the growing role of the anthropologist in detecting signs of trauma. Finally, the relatively new role of the forensic anthropologist in the domain of identification of the living is described, although this area is still underrepresented as regards research activity: these studies concern the strive to devise methods for identifying faces (e.g. in the case of crimes registered by videosurveillance systems), aging living individuals or juveniles represented in pedopornographic material.

Dental amalgam and mercury levels in autopsy tissues: food for thought.

Eighteen cadavers from routine autopsy casework were subject to a study of tissue levels of total mercury in brain, thyroid, and kidney samples by atomic absorption. On these same cadavers, all dental amalgam fillings (the most important source of inorganic mercury exposure in the general population, according to the World Health Organization (WHO) were charted. Total mercury levels were significantly higher in subjects with a greater number of occlusal amalgam surfaces (>12) compared with those with fewer occlusal amalgams (0-3) in all types of tissue (all P < or = 0.04). Mercury levels were significantly higher in brain tissues compared with thyroid and kidney tissues in subjects with more than 12 occlusal amalgam fillings (all P < or = 0.01) but not in subjects with 3 or less occlusal amalgams (all P > or = 0.07).
