Every year Australian homicide detectives investigate around 400 suspicious deaths. In eighty per cent of cases the victim knew their killer, and some of them knew their killer intimately - when wife kills husband, husband kills wife, parent kills child, child kills siblings and/or parent, and lover slays lover. These crimes have an especially chilling fascination that stems from the shock and disbelief we feel at such an appalling betrayal of trust. BLOOD TIES describes in gripping detail a number of cases where a family member or intimate companion took the life of a loved one. These include the case of Wendy Lange, who mixed sleeping tablets into her husband's mashed potato before having him killed; Jeffrey Gilham, found guilty of slaying his parents and older brother in 2009; and Brian Corrigan, who murdered his seven months pregnant wife. Police investigators, the victims' family and friends and psychologists all shed light on why a loved one would commit murder. |
