- Ms Dempsey, a devoted mother of five, suffered a medical incident in the watch house, but police are awaiting toxicology results to confirm cause of death
- Lawyers for the family slam the NT government, saying the death is a ‘devastating indictment of systemic failure’ and demanding action to prevent similar tragedies
- Ms Dempsey’s death is the 34th Aboriginal death in custody in 2025, and the fourth in the Northern Territory, sparking widespread grief and anger in the community
A heartbroken community is mourning the loss of Aboriginal mother Kumanjayi Dempsey, who tragically died in police custody at the Tennant Creek watch house on Christmas Day. The 44-year-old mother of five was arrested for aggravated assault and spent just two days in the watch house before her life was cut short.
Lawyers for the family, O’Brien Criminal and Civil Solicitors, have launched a scathing attack on the NT government, saying Ms Dempsey’s death is a ‘devastating indictment of systemic failure’. In a statement, the firm said: ‘We extend our sincere condolences to Kumanjayi’s family, friends and loved ones and ask that their privacy be respected during this trying time.’
NT police believe Ms Dempsey suffered a ‘medical incident’ in the watch house, but are awaiting the results of toxicology testing to confirm the cause of death. However, multiple sources have confirmed that she suffered from rheumatic heart disease, a potentially deadly heart condition caused by repeated streptococcal infections.
Despite this, Ms Dempsey did not disclose her condition during a medical assessment when she was taken into custody. The NT government had begun stationing nursing staff at watch houses in Darwin, Katherine and Alice Springs, but not in Tennant Creek, sparking questions about the adequacy of medical care in the facility.
In the wake of Ms Dempsey’s death, floral tributes have been left outside Tennant Creek Police Station, as the community struggles to come to terms with the loss of a beloved mother and member of the community. The NT government has launched an investigation into the death, but lawyers for the family are demanding more.
‘Kumanjayi’s death is particularly harrowing given the NT government’s recent refusal to allow the UN Working Group on Arbitrary Detention to conduct its scheduled inspection of Northern Territory detention centres, including watch houses,’ the lawyers said. ‘The NT government must be held accountable for this tragedy and take immediate action to prevent similar deaths in the future.’
