Overview
- Police charged 70-year-old Maria Arrieta with one count of murder recorded as domestic violence after a multi-year homicide inquiry.
- The victim, Isaac “Ike” Oar, was found unresponsive in Ayr on August 10, 2023 and was later confirmed to have weighed just 29 kilograms.
- Detectives told reporters that their investigation examined Oar’s health and care across his life and concluded he had not had professional medical treatment for well over a decade.
- Authorities say Arrieta is Oar’s half-sister and worked as a disability support worker, a fact that raises questions about who managed his daily care and how those arrangements were overseen.
- Arrieta is due to appear in Brisbane Magistrates Court and the case is expected to intensify scrutiny of how disability supports and the NDIS monitor vulnerable people’s health and welfare.
