Changing patterns of female suicide: 1986-2000.

A study was undertaken of the rates and methods of female suicide observed at the Forensic Science Centre in South Australia over a 15 year period from 1986 to 2000. A total of 609 cases of female suicide were found (age range= 13-88 yrs; mean= 44 yrs), with 249 drug overdoses, 114 hangings, 100 deaths due to carbon monoxide (CO) toxicity, 40 drownings, 35 firearm deaths and 71 miscellaneous deaths (including deaths due to self-immolation, jumping from heights and incised wounds). The most common age range was 26-50 yrs in all categories except for drowning where victims tended to be older. While overall suicide rates in females remained unchanged, with no changes in the rates at different ages, significant increases in hanging and CO deaths occurred over all age groups (p < 0.05), with significant falls in drug overdose deaths in the 10-25 year age group (p < 0.01), and significant overall falls in suicides due to gunshot wounds (p < 0.05). No changes were observed in female suicides due to drowning. This study has demonstrated, therefore, that although no changes in overall suicide rates for females occurred, there have been alterations in the types of methods being used. Although drug related deaths remained the largest category, hanging deaths, which were once uncommon in females, have increased markedly.

Clinicopathologic features of fatal self-inflicted incised and stab wounds: a 20-year study.

The files of the Forensic Science Center in Adelaide, South Australia, were examined for all cases listed as suicide in which death had been caused by the use of a sharp instrument during the 20-year period from January 1981 to December 2000. Fifty-one cases were identified, consisting of 35 men and 16 women. The age range was 23 to 83 years (mean 49 years) representing 1.6% of total suicides (513182). Fatal injuries included incised wounds to the arms in 51.4% of men (n = 1835) compared with 87.5% of women (n = 1416), incised and stab wounds to the neck in 40% of men (n = 1435) and 25% of women (n = 416), and stab wounds to the chest or abdomen in 28.6% of men (n = 1035) and 12.5% of women (n = 216). In 8 cases, multiple sites were involved. The use of sharp instruments in suicide was favored by older, rather than younger, individuals, with a tendency for women to incise their wrists. Hesitation marks were present in 23 cases (54%) and scarring of the wrists from previous suicide attempts in 5 cases. Although this study demonstrated a higher number of men than women committing suicide by using sharp objects, this method of suicide remains uncommon.

Gasoline exposure in motor vehicle accident fatalities.

Three cases are described in which deaths after motor vehicle accidents occurred as a result of positional asphyxia associated with exposure to gasoline. The deceased individuals were aged 16, 34, and 35 years, respectively (M:F = 1:2) and had all been in the back seat of motor vehicles involved in rollover accidents that had resulted in spilling of gasoline with contamination of the cabins. Major components of gasoline were detected in blood and tissues by headspace gas chromatography. Postmortem toxicologic investigations of such cases, which include analyses for volatile hydrocarbons, may therefore produce additional significant information.
