A retrospective review was undertaken in South Australia over an 11-year period, 1996-2007, of all multiple, unnatural deaths in adults looking for cases of double suicide & murder-suicide. 7 cases of double suicide involving 14 individuals (9 males, 5 females) & 8 murder-suicides involving 16 individuals (9 males, 7 females)were identified. While differentiating between the groups may be difficult, double suicide victims used much less violent methods than perpetrators of murder-suicide & often had histories of chronic debilitating disease. Spousal & familial links characterised both groups. (25 refs.)
