Avulsion of the distal tibial shaft in aircraft crashes: a pathological feature of extreme decelerative injury

A pilot and his passenger were killed on impact with the ground when their light aircraft crashed. Both deaths were caused by extensive injuries involving severe craniocerebral, skeletal, soft tissue, and organ trauma. In both victims, the legs were shortened, with stripping of muscle and soft tissues from the shafts of the lower limb long bones. In addition, fragments of distal tibial shaft had been forced through the soles of the victims' shoes. This sign indicated a fall from height and showed that the direction of the decelerative forces had been along the axis of the legs and that the force of impact was severe enough to cause fracturing of the lower limb bones, with subsequent extrusion of bone fragments downwards through the shoes. When present, this observation represents another feature at autopsy that can add to the understanding of the circumstances of a fatal air crash and the position of the victims immediately prior to impact.     

Dimensions of adolescent self-images

Using techniques derived from information theory, structural dimensions of adolescent self-images were studied. Within a sample of 58 adolescents, patients and normals, a variety of self-images were obtained using a specially designed Q-sort. The initial hypothesis predicted, on the basis of previous findings, that the idealized self-images would be more polarizedfor the patients. This hypothesis was only partiallyconfirmed. the self-idealization was significantly more polarized in the patient group. But the other two idealizations (those based on parental expectations) did not reflect a patient-normal difference. Rather, a significant three-way interaction of sex, age, and psychiatric status was found for these self-images, as well as for the current self-image. The consistent pattern in these three-way interactions was that late-adolescent boys polarized their self-images if they were in the normal group and had structurally complex (nonpolarized) self-images if they were in the patient group. The paper concludes by discussing the meaning of these findings. A framework for interpreting polarization is proposed and applied to the results. In addition, the notion of a Self-Image Profile is formulated and further elaborated. Finally, the relevance of these studies to other personality research and clinical observations is considered.This investigation was supported in part by a Research Scientist Development Award, Number K1-70-178, to S.T.H.Received M.A. in social anthropology from Harvard University and M.D. from Yale University.

Unusual facial markings and lethal mechanisms in a series of gasoline inhalation deaths

A review of deaths associated with hydrocarbon toxicity from gasoline sniffing in South Australia throughout a 10 year period from July 1987 to June 2002 revealed 4 cases. The victims were all Aboriginal people from remote inland communities. Each death had occurred while the victim was lying in bed sniffing gasoline from a can held to the face. Once unconsciousness had occurred, the mouth and nose had been pressed firmly against the can by the weight of the head. In each case, the effects of gasoline toxicity had been exacerbated by hypoxia and hypercapnia from rebreathing into the container once a tight seal had been established between the face and the can. The circular impressions left by the can edges on the faces of each of the victims provided an autopsy marker that assisted in clarifying the details of the fatal episodes. Discouraging solitary gasoline sniffing in bed may reduce the death rate in communities where this behavior is practiced.     

Sometimes What Everybody Thinks They Know Is True

This essay responds to D. Davis and W. C. Follette (2002), who question the value of motive evidence in murder cases. They argue that the evidence that a husband had extramarital affairs, that he heavily insured his wife's life, or that he battered his wife is ordinarily of infinitesimal probative value. We disagree. To be sure, it would be foolish to predict solely on the basis of such evidence that a husband will murder his wife. However, when this kind of evidence is combined with other evidence in a realistic murder case, the evidence can be quite probative. We analyze cases in which it is virtually certain that the victim was murdered but unclear who murdered her, and in which it is uncertain whether the husband murdered the wife or she died by accident. We show that in each case motive evidence, such as a history of battering or of infidelity, can substantially increase the odds of the husband's guilt. We also consider the actual case on which Davis and Follette base their paper. We argue that testimony of Davis on the basis of the analysis presented in their paper was properly excluded, for it would have been misleading and unhelpful.
