From verbal abuse to axe murder: The death of Canberra mum Tara Costigan

Three years ago Marcus Rappel murdered 28-year-old Tara Costigan with an axe. The murder continues to confront our definition of domestic violence because despite a pattern of verbal aggressions, Rappel had never previously physically abused Costigan, the mother of his child. Canberra journalists Elizabeth Byrne and Susan McDonald investigate how health professionals, and law enforcement could have prevented the death, were they equipped with the right information at the right time. Family members of both Tara Costigan and Marcus Rappel speak out for the first time since the death. This is a repeat of a program that aired in July 2018.
