The reconstruction: a useful tool in forensic sciences.

The intervention of a forensic pathologist may be required at any stage of a judicial investigation. Clearly, he or she plays an important role at a crime scene and later on during the examination of the body. But the forensic pathologist's contribution is equally important during reconstruction, which is most frequently called for in cases of violent deaths, homicides in particular. However, reconstruction may also be very useful in cases of less importance in terms of criminal law. It requires little investment and can provide precious evidence. In the two cases presented here we were able to exclude, respectively, the presumption of the adulteration of a blood sample taken for alcohol dosage and the accidental origin of an attempted murder. In fact, reconstruction may be a valuable procedure in any event requiring the participation of a forensic expert.

The challenge of identification following the tragedy of the Solar Temple (Cheiry/Salvan, Switzerland).

On October 5, 1994, 48 members of the Sect of the Solar Temple were found dead at two different locations in Switzerland: 23 victims in Cheiry and 25 victims in Salvan. Our Institute was commissioned to solve the forensic problems presented by this tragedy. Our goals were to establish the time of death, determine its causes, help elucidate the surrounding circumstances and identify the victims. This work presented us with the following challenges. This catastrophe was of an 'open' type: there was no list of 'passengers'; the victims were of five different nationalities and many had just arrived in Switzerland to participate in this event; family ties were very complex within this group; half of the victims were burned and sometimes charred; the exceptionally intense media converage of the story put a lot of pressure on the investigators and our Institute. In spite of these difficulties, all the victims were positively identified within 1 month. In the present report, we describe the steps realized to progress in our work. A special section describes our relationship with the journalists and their invaluable help in our investigations. The importance of being prepared for such an event is discussed.

Forensic diaphanoscopy: how to investigate invisible subcutaneous hematomas on living subjects.

A significant proportion of subcutaneous hematomas remain undetected after external visual examination of the body. In the case of a cadaver such hematomas can be easily identified through a cutaneous incision but in living persons the diagnosis becomes more complicated. The usual methods, based on diagnostic imaging, do not combine sufficient reliability and feasibility. The results of our investigations demonstrated that forensic diaphanoscopy is a highly sensitive (95%) and specific (97%) means to determine the presence or absence of subcutaneous invisible hematomas. In addition, it is possible to locate such hematomas with great precision, to draw their shape and evaluate their magnitude. The lower limit of detection is of the order of 1 mm. The advantages of this method lie in the fact that it is reliable, non-invasive, has no side effects, is simple to carry out and allows real time scanning.

Experimental evaluation of rigor mortis. VIII. Estimation of time since death by repeated measurements of the intensity of rigor mortis on rats.

The development of the intensity of rigor mortis was monitored in nine groups of rats. The measurements were initiated after 2, 4, 5, 6, 8, 12, 15, 24, and 48 h post mortem (p.m.) and lasted 5-9 h, which ideally should correspond to the usual procedure after the discovery of a corpse. The experiments were carried out at an ambient temperature of 24 degrees C. Measurements initiated early after death resulted in curves with a rising portion, a plateau, and a descending slope. Delaying the initial measurement translated into shorter rising portions, and curves initiated 8 h p.m. or later are comprised of a plateau and/or a downward slope only. Three different phases were observed suggesting simple rules that can help estimate the time since death: (1) if an increase in intensity was found, the initial measurements were conducted not later than 5 h p.m.; (2) if only a decrease in intensity was observed, the initial measurements were conducted not earlier than 7 h p.m.; and (3) at 24 h p.m., the resolution is complete, and no further changes in intensity should occur. Our results clearly demonstrate that repeated measurements of the intensity of rigor mortis allow a more accurate estimation of the time since death of the experimental animals than the single measurement method used earlier. A critical review of the literature on the estimation of time since death on the basis of objective measurements of the intensity of rigor mortis is also presented.

An unusual case of sudden death in an alcohol addict.

The sudden and unexpected death of a 40-year-old female alcohol addict is described. At the autopsy recent rib fractures were found. The extremity of one fractured rib had caused a massive haemorrhage by erosion of a coronary artery.

Experimental evaluation of rigor mortis. VI. Effect of various causes of death on the evolution of rigor mortis.

The evolution of rigor mortis was studied in cases of nitrogen asphyxia, drowning and strangulation, as well as in fatal intoxications due to strychnine, carbon monoxide and curariform drugs, using a modified method of measurement. Our experiments demonstrated that: (1) Strychnine intoxication hastens the onset and passing of rigor mortis. (2) CO intoxication delays the resolution of rigor mortis. (3) The intensity of rigor may vary depending upon the cause of death. (4) If the stage of rigidity is to be used to estimate the time of death, it is necessary: (a) to perform a succession of objective measurements of rigor mortis intensity; and (b) to verify the eventual presence of factors that could play a role in the modification of its development.

[Responsibility in the prevention of accidents of the most exposed pedestrians: children and elderly persons].

A study has been carried out on the Swiss road accidents statistics involving pedestrians. The most exposed road users (young and aged pedestrians) are the ones best protected by traffic law. However, data suggest that these pedestrians are more frequently declared responsible for the accidents in which they are involved. Arising from this contradiction, both the notion of responsibility and the way the prevention of these accidents is conceived should be queried.
