Analysis of a series of deaths between 1986 and 2001 resulting from natural disease, accidents, suicides, and homicide, where postmortem animal activity had traumatized bodies, was undertaken at the Forensic Science Center in Adelaide to demonstrate the range of lesions that may occur and problems in interpretation that result. Tissue damage had been caused by a variety of animals, including fly larvae, ants, birds, dogs, rodents, sea lice, and sharks. Postmortem animal activity had disguised injuries, modified wounds, and created the appearances of inflicted injury. Problems with identification occurred after postmortem facial trauma, and loss of organ parenchyma had interfered with, or precluded, the precise determination of the manner of death in some cases. Specific kinds of tissue and organ damage may occur after death, necessitating careful assessment of lesions in a search for characteristic features of animal activity. The pattern of lesions may enable identification of the particular species of animal involved.

The number of deaths due to amphetamine derivatives apparently due to substitution of PMA for MDMA (Ecstasy) have recently increased markedly in Adelaide. Potential users should be warned that PMA has been associated with a much higher rate of lethal complications than other designer drugs, and that no guarantee can be made that tablets sold as Ecstasy are not PMA.

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.
