Abstract
A retrospective study of cases of drowning suicide was undertaken at the Forensic Science Centre in Adelaide, South Australia for the period April 1980 to March 2000. A total of 123 cases were found, with 76 males (age, 16–88 years; average, 50.5 years; standard deviation [SD], 20.1 years) and 47 females (age, 34–88 years; average, 60.6 years; SD, 13.9 years). There were 66 fresh water drownings and 57 saltwater drownings. Female victims were significantly older than male victims for both fresh water and saltwater drownings (P < .05 and P < .01, respectively). Deaths in young women were rare. No temporal trend in drowning suicides could be shown, with annual numbers varying from 0 to 12 cases (average, 6.15; median, 7). Women preferentially chose the ocean or bath to drown themselves in, whereas males chose rivers, ditches, and lakes. Swimming pools were rarely used for suicide in this population; alcohol use was not usual; and there was often a significant history of mental illness.
