Defendants pleading insanity: an analysis of outcome

The authors examined the cohort of all defendants pleading not guilty by reason of insanity over a 12-month period in Baltimore City's superior trial court. During that time, 143 of the 11,497 defendants indicted (1.2%) pled not criminally responsible. Fourteen of those defendants (10%) were subsequently found not guilty by reason of insanity. The authors found marked agreement between the prosecution and defense with only two cases leading to full trials where the issue of insanity was argued. The evaluating physician's opinion as to criminal responsibility and Axis I diagnosis, and the most serious underlying charge discriminated between those defendants found not guilty by reason of insanity and those defendants found guilty or not guilty by the court. Other demographic factors such as age, number of dependents, educational level, severity of illness, and criminal background did not discriminate between the two groups.     

The role of hydrogen cyanide and carbon monoxide in fire casualties: a prospective study

Determinations of blood cyanide and carboxyhemoglobin concentrations were performed in 18 victims found dead in buildings after fires during a 2-year period. The results indicated that 50% of the victims had been exposed to toxic levels of hydrogen cyanide and 90% to toxic levels of carbon monoxide. Lethal concentrations of carbon monoxide were found in 83% of the victims. In one case a lethal blood cyanide but a non-toxic blood carboxyhemoglobin value was found. It is concluded that carbon monoxide appears to be more important than hydrogen cyanide as a toxic agent in the fire atmosphere, but cyanide poisoning without carbon monoxide poisoning may, under certain circumstances, be the cause of death in fire victims.     

Health care costs and personal bankruptcy

In response to published but unconfirmed reports that health care costs were a leading cause of personal bankruptcy in the U.S., court records of all bankruptcy petitioners in one judicial district were examined. The records were analyzed by income, employment, debt categories and amounts. Within the limitations of the study, health care costs seem not to have played a significant role in the financial lives of this population.     

Comparison of gunshot wounds and field-tipped arrow wounds using morphological criteria and chemical spot tests

Arrow wounds represent an unusual class of wounds rarely seen by most death investigators. Although the edged, broadhead-tipped arrow produces a wound usually characteristic of archery/crossbow weapons, the plain, field-tipped arrow wound can be confused with gunshot injuries in those cases in which powder residue or firearm projectiles or fragments or both are not recovered. We present a case of a deer carcass with a wound of uncertain firearm or archery origin which initiated a comparison of firearm wounds and archery wounds on fresh road-killed deer. We found the following features to be valuable in the differentiation of gunshot wounds and field-tipped archery wounds: First, the majority of the gunshot wounds (but none of the arrow wounds) had identifiable, macroscopic, wipe-off material and chemically identifiable wipe-off residue by spot test. Second, the archery wound defects had very inconspicuous abrasion rings as compared to the often prominent abrasion rings of gunshot wounds. Third, the actual central defect in the archery wounds was more likely to be oblong or slit-like compared to the gunshot wound defects, which were more likely to be round.     

Capgras syndrome and dangerousness

The determination of glyoxalase I phenotypes in human bloodstains

A method is described for the determination of glyoxalase I phenotypes in liquid blood and dry bloodstains. The frequencies of glyoxalase I phenotypes in various populations of S.E. England are included.
