A study of homocide perpetrated by fire was performed on the case files of the Office of the Medical Examiner of Metropolitan Dade County in Miami, Florida, during the years from 1977 until 1984. A total of 26 cases were collected and analyzed as to age, race, sex, and the cause of death of the victim along with the blood alcohol content, the drugs detected at autopsy, and the blood carboxyhemoglobin level. Additionally noted were the geographic location of the terminal incident, the scene circumstances, how the fire started, who started the fire, and the reason for the fire. The most common victim was a 31-50-year-old white man who died from smoke inhalation while sober. Commonly, drugs detected were negative, and the carboxyhemoglobin levels were elevated. The fire occurred at "home" while the victim was sleeping. Usually, a flammable liquid was poured and ignited by a drifter who was a brief acquaintance and earlier involved in an argument with the victim.
I studied 25 cases of suicide in people diagnosed as having the acquired immunodeficiency syndrome (AIDS) or who thought that they had that disorder, during 1985-1989. Case reports are presented. A discussion ensues concerning the occurrence of this phenomenon and the medical examiner's role in AIDS' public health situation in general.
Accidental fire deaths that occurred in Metropolitan Dade County, encompassing Miami, Fla., USA, during the years from 1979 until 1983 were studied. A total of 108 cases were collected, representing 6.1% of the nontraffic-related accidents during this 5-year period, and analyzed as to the age, race, sex, cause of death of the victim along with the blood alcohol content at autopsy, toxicologic analysis, location of the fire, and how the fire started. Essentially, the victims ages cluster in the 0-5 years and does 70 years, although other age groups are evenly distributed. A white male population predominates. The cause of death is listed as either smoke inhalation or thermal injury. Most toxicologic analyses were not performed due to the high rate of fire rescue intervention and at least emergency room hospitalization prior to death. Carboxyhemoglobin levels, when analyzed, ranged from less than 20% to over 80%. In a smaller group of cases, cyanide was analyzed for and was found negative (or none detected) in the majority of the cases. More fires occurred in residences and started due to cigarette smoking or electric malfunction.
Examination of gunshot wounds can frequently be obscured by dried blood and other extraneous artifacts. This note describes a method that involves irrigation of the wound with commercial hydrogen peroxide (3% by volume), which enhances the wound without altering the abrasion ring or powder residues.
