A Croppa Creek man accused of shooting dead an environmental compliance officer has been refused bail in Moree.
Police laid two fresh charges against 79-year-old farmer Ian Robert Turnbull, including detaining a person with intent to commit a serious indictable offence and common assault, as he appeared via video link in Moree Local Court on Tuesday.
He is already charged with one count of murder after he allegedly shot Tamworth-based Office of Environment and Heritage compliance worker and father-of-two Glen Turner a number of times on July 29.
Mr Turner died at the scene.
Police allege Turnbull detained a colleague of Mr Turner, preventing him from assisting and providing aid to the deceased as they stopped to inspect a remote road reserve north of Moree.
Appearing via video link from the maximum security centre in Cessnock, Turnbull has been in custody since he was arrested at his Croppa Creek home near the alleged murder scene.
As part of a fresh release application, barrister for Turnbull, Hament Dhanji SC, submitted a 10 point "regime" for his client to be released on bail and reside in Sydney while the case progresses.
He said his client could raise more than $5 million as surety and report to Mosman police daily to mitigate any risk of failing to appear and ensuring the safety of the community by living away.
The DPP said Turnbull posed three unacceptable risks and has "disclosed an intention to kill" and shown "a callous regard for human life".
The court heard Turnbull allegedly fired five shots on the night, with three said to have hit Mr Turner in the chin, the left shoulder and the back, while another pierced his shirt.
Magistrate Darryl Pearce said the seriousness of the alleged offence was "extremely high" and if convicted, it was likely Turnbull would "serve out the rest of his natural life in jail for murder."
Mr Pearce said because of the background of the land clearing dispute in the local area and the cases involving the Turnbull family already before the Land and Environment Court, no amount of money or conditions could mitigate the risks.
"Bail is refused," he told the court.
