Six years after Senior Constable Brett Forte was shot in a hail of bullets, the coroner will deliver his findings into the deaths of the Queensland police officer and the man who killed him.
Sen Const Forte, 42, died after Ricky Maddison opened fire on police vehicles in the Lockyer Valley, west of Brisbane, on May 29, 2017.
Maddison, 40, was later shot dead after being warned to surrender more than 80 times during a 20-hour siege.
He had fired at police, including at a helicopter, 21 times.
Maddison had been on the run and hiding in a rural stronghold for more than two months, avoiding an arrest warrant for a domestic violence incident.
He had accused authorities of unfairly targeting him, and refused to go to a police station.
Maddison called police on the day of Sen Const Forte's death, refusing to surrender.
Police spotted his vehicle in Toowoomba and followed him on the Warrego Highway, before Maddison ambushed them on a dirt road.
He opened fire on police vehicles with automatic weapons, peppering Sen Const Forte's car with 27 bullets.
Sen Const Forte urgently reversed but the vehicle rolled, trapping him and his partner inside.
Sen Const Forte was hit at least twice and he bled out within minutes.
A 2021 inquest into their deaths was held in Toowoomba before State Coroner Terry Ryan.
The inquest looked at the interaction between police and Maddison in the lead-up to the deaths, previous attempts to locate him, and management of the pursuit.
It also examined siege management strategies and the events leading to the decision to shoot Maddison.
The coroner will deliver the inquest findings at 10am AEST on Tuesday.
