Suicide by electrocution with low-voltage current

Three cases of suicide by electrocution with low-voltage current were observed in five years (1994-1998) by medical clinical forensic examiners of an Emergency Forensic Unit of the Paris suburb among 2,000 external death examinations. The cases involved one woman, aged 72 and two men, aged 38 and 41. In the last two cases, electric burns were retrieved under bared electric wires, placed on the arms or fingers in order to realize a hand-to-hand electric circuit involving the heart muscle. In the other case, the electric circuit between mouth and foot also involved the heart muscle. Household low-voltage current delivered (220 V in France) had a sufficient strength to induce local muscular paralysis and heart fibrillation. In the three cases, blood samples taken have retrieved very high levels of muscular enzymes (CPK, LDH) correlated to the mechanism of electric death. The rareness of suicide by electrocution and its forensic characteristics are detailed in order to help the clinical forensic examiners, prosecutors, and police officers concerned by such death examinations.     

Detection of semen in stains on material evidences by quantitative immunofluorescence test

Russian and foreign methods used in forensic medicine for detection of the semen in stains on material evidences are compared. The potentialities of quantitative immunofluorescence test for detection of the semen in stains on material evidences, developed at Bureau for Forensic Medical Expert Evaluations of the Leningrad region, are described. Unlike other methods used in Russia, this method detects the semen in stains in the absence of spermatozoa and in stains with very low amount of the semen. Our modification allows objective recording of the results with computer processing. The method is cheaper than its foreign analogs and its sensitivity is similar to them.     

Isolation of nitrobenzene from biological material

Toluene is recommended as an agent for extraction of nitrobenzene from biological material. Optimal conditions for nitrobenzene isolation from cadaveric human liver are defined and the results of isolation are quantitatively evaluated.     

Asphyxial death during prone restraint revisited: a report of 21 cases

Determining the cause of death when a restrained person suddenly dies is a problem for death investigators. Twenty-one cases of death during prone restraint are reported as examples of the common elements and range of variation in these apparently asphyxial events. A reasonable diagnosis of restraint asphyxia can usually be made after ruling out other causes and collecting supportive participant and witness statements in a timely fashion. Common elements in this syndrome include prone restraint with pressure on the upper torso; handcuffing, leg restraint, or hogtying; acute psychosis and agitation, often stimulant drug induced; physical exertion and struggle; and obesity. Establishing a temporal association between the restraint and the sudden loss of consciousness/death is critical to making a correct determination of cause of death.     

Empathy and Jurors' Decisions in Patricide Trials Involving Child Sexual Assault Allegations

In a mock-trial paradigm, 205 participants considered a patricide trial in which a child defendant claimed the patricide was done in self-defense after years of sexual abuse. Participants in an empathy-induction condition were asked to take the perspective of the defendant and to detail how they would be thinking and feeling if they were the defendant. Control condition participants received no such instructions. Results indicated that, compared to jurors in the control condition, jurors who were asked to take the defendant's perspective had more empathy for the defendant (without feeling more similar to or more sympathy for the defendant), found the defendant less guilty and less responsible for the murder, and were more likely to consider abuse to be a mitigating factor in the killing. Overall, compared to men, women were more likely to believe the defendant's abuse allegations, find the defendant credible, and consider the defendant to be less responsible for the murder. Women in the empathy condition found the defendant less guilty than did all other jurors. Finally, child defendant gender was also varied, but this had few effects on case judgments overall. Jurors, however, were more likely to believe that the girl defendant was sexually abused than the boy defendant. We discuss theoretical implications for understanding the social psychological construct of empathy as well as implications for understanding jurors' decisions in cases involving child sexual assault allegations.     

Persian leopard (Panthera pardus) attack in Oklahoma: case report

The authors report a fatal case of a Persian leopard (Panthera pardus) attack in an animal sanctuary in Oklahoma. The victim was a 53-year-old Costa Rican woman who was attempting to feed the animal when she was attacked and killed. Autopsy, radiography, fingerprint analysis, microbiologic cultures, and dental impressions were used to evaluate the case. These simple techniques can be applied to similar cases involving wild and domestic animal attacks.
