Evidence for use of electroshock devices

The authors tested whether use of an electro shock weapon (stun gun) leaves marks on skin which can be found in an exterior examination. On pig skin such marks could not be produced postmortally. An experiment on one of the authors caused reddish skin marks which persisted for about 2 h. Inability to act as promised by the weapons' manufacturers did not occur in our experiments, exactly as previously described by other authors. Use of an air tester which shoots barbed electrodes ought to produce bleedings if the electrodes actually penetrate the skin.     

Determination of drug levels in larvae of Protophormia terraenovae and Calliphora vicina (Diptera: Calliphoridae) reared on rabbit carcasses containing morphine

Two species of blow flies (Diptera: Calliphoridae) were reared on tissues from rabbits administered different dosages of morphine. These species, Protophormia terraenovae and Calliphora vicina are among the first wave of insects colonizing a dead body. Two series of 3 rabbits were given dosages of 10, 20, and 40 mg/h of morphine over a 3 h period via ear artery perfusion. A morphine blood level plateau was attained after 1 h of perfusion. Two other rabbits were used as controls. Samples of tissues collected from rabbits using a coelioscopic technique were determined to have morphine concentrations similar to those encountered in human overdoses and were correlated with dosages of morphine administered. All samples from control rabbits were negative for morphine. Larvae and puparia of both species were regularly collected from each rabbit for toxicological analysis. Concentrations of morphine in larvae reared on rabbit carcasses containing morphine were significantly lower than concentrations found in the tissues. There was a decrease in concentration in morphine observed in transition from feeding 3rd instar larva to puparium. A correlation between larval concentration and tissue concentration was found only in feeding 3rd instar larvae.

The New Water Legislation of Zimbabwe and South Africa – Comparison of Legal and Institutional Reform

Recently, several new pieces of water legislation have been promulgated in both Zimbabwe and the Republic of South Africa. The new acts are an attempt to correct injustices of a colonial past and to trigger development towards effective, equitable and efficient integrated water resources management influenced by the policy decisions in Agenda 21 and the need to respect economic and social human rights. This article aims at identifying and describing factors of prime importance in the process of legal and institutional reform. Major factors are earmarked and derived from the proceedings in Zimbabwe and are compared with the situation in South Africa. Thorough analysis by the author of proceedings, preambles, memoranda, legislation and addenda has induced roughly 5 major reform issues: The call for equitable water distribution based on a widely consented water resources management strategy; The need for effective and efficient integrated water resources management conducive to stakeholder participation through decentralisation processes; The redressing of legal shortcomings in former water legislation with the emphasis on the introduction of integrated approaches; The introduction of instruments of cost recovery for water resources management; The need to develop human resources capacity and institutional strength within the implementing agencies.For both Southern African states, these issues appear to be of comparable importance as major triggers for legal and institutional reform, although not always in the same sense.The resulting most important legal and institutional changes are presented, discussed and compared. Finally, prospects for and constraints on implementation of the new water legislation in these countries are compared.     

A shot through the window

At issue in this case was whether an unusual window defect seen in two of the crime scene photographs was due to a bullet and if so, if that same bullet fatally wounded the victim. The window appeared to have been cracked prior to the apparent shot through it. A .22 bullet recovered from autopsy, when examined only by light microscopy, failed to show associated glass fragments. A previously cracked test window was shot a number of times with .22 caliber bullets near the cracks in an effort to simulate the window defect seen in the crime scene photographs. Several of the defects produced by the test window shots appeared similar to the crime scene window defect. The .22 bullet taken from the victim and several of the test bullets (collected by a cotton box) were examined by scanning electron microscopy/energy dispersive X-ray spectroscopy. The test bullets showed glass particles on and embedded in their surfaces. Particles of similar size and composition were found embedded in the surface of the bullet from the victim. The bullet likely struck the window prior to hitting the victim. It was apparent by the morphology of some of the mushroomed test .22 bullets that they hit the window crack. These bullets showed that the glass on one side of a crack often fails before the other side during the strike. Aggregations of powdered glass on many of the mushroomed surfaces of the .22 bullets suggest that as the bullet mushrooms during impact on the window surface, the glass in contact with the bullet powderizes and coats the mushroomed surface of the bullet with a layer of fine glass particles.     

Criminals' explanations of their criminal behavior, III: the effects of time and context

The authors looked at the explanations for their index of violent crimes as given by 69 incarcerated violent male offenders, respectively. We then examined the extent to which those explanations changed with the passing of time and with change in context. We found that explanations of impaired internal control increased with the passing of time, and that such explanation was given more often to mental health professionals rather than law enforcement professionals. Finally, we found that our subjects tended to give mental health professionals fewer explanations involving external control with the passing of time.     

Delusional misidentification and aggression in Alzheimer's disease

Alzheimer's disease has been associated with serious behavioral disturbances including aggressive behaviors and agitation. Aggression in dementia of the Alzheimer's type may be associated with psychotic symptoms, particularly delusional misidentification phenomena. These phenomena are complex and varied in Alzheimer's disease and so far have been only rudimentarily described. In this paper, we explore the association of delusional misidentification and aggression in an individual suffering from Alzheimer's disease.     

Combined homicide-suicide in Galveston County

Combined homicide-suicides have been classified based on the psychopathology of the perpetrator and the nature of the relationship between perpetrator and victim(s). To further understand the nature of this tragic phenomenon and to test the validity and practicality of a previously suggested classification system, investigators systematically collected data on all combined homicide-suicide events that occurred in Galveston County, Texas over a continuous 18-year period (n = 20). The most common psychopathological finding for perpetrators was high serum alcohol levels that suggested intoxication. Most combined homicide-suicides fell into one of the relational categories and most of these, as predicted, were of the consortial type, possessive subtype. As expected, due to the small sample size, the less common types of combined homicide-suicide were not represented in this sample.
