A terror suspect killed an elderly couple while on bail after a monitoring company's "failure" to notify specialist police of his tracking device's removal, a coroner has found.
Raghe Mohamed Abdi, 22, was shot dead by Queensland Police on the Logan Motorway at Drewvale in Brisbane's south on December 17, 2020.
Officers were responding to reports of a man walking on the verge of the motorway when Abdi pulled out a knife and ran at them yelling "Allahu akbar".
Police later discovered that Maurice Antill, 87, and his wife, Zoe Antill, 86, had been bashed and stabbed to death in their home in the nearby suburb of Parkinson.
Deputy State Coroner Stephanie Gallagher has released her findings into the three deaths following inquest hearings in July 2023 and March 2024.
Ms Gallagher found police used appropriate force when they fatally shot Abdi as he kept advancing despite the officers moving away and giving him time to comply with commands to drop his knife.
She also found Mr and Mrs Antill were killed by Abdi in an apparently random attack.
"It will be very difficult for Maurice and Zoe's family to hear that we will never know exactly why Raghe took the actions that he did," Ms Gallagher said in her findings.
