EYES red and filled with tears, Ian Robert Turnbull was clearly distraught as he was led into the dock of Moree Local Court on Wednesday.
About 14 hours beforehand the 79-year-old long-term Croppa Creek resident was captured by police after allegedly ambushing two Office of Environment and Heritage workers, before pulling a gun on them.
Police Prosecutor Crystal Jones told Moree Local Court that 51-year-old Tamworth man Glendon Turner and his colleague were attending the Croppa Creek property to carry out duties.
"Without warning, shots were fired towards the deceased and the witness," she said. "There were a number of shots."
The court heard it was a bullet that struck Mr Turner in the back that was the fatal hit.
A blow allegedly delivered by Turnbull as the compliance officers men tried to carry out an investigation in the Talga Lane area after reports of illegal land clearing in the Croppa Creek region.
Mr Turner's colleague escaped unharmed but was in a state of shock after the traumatic events.
Turnbull sat motionless in the dock, supported by two family members in the court, as he faced one count of murder.
Magistrate Darryl Pearce said the serious allegations meant if convicted, Turnbull would likely serve out a term in prison.
"I'm refusing bail," he told the court.
Turnbull's solicitor Sylvestor Joseph made no application for release in yesterday's brief proceedings, but noted the accused reserves the right to make further applications for bail down the track.
The family made no comment and brushed waiting media outside after Turnbull was led back to police cells before being transported to a correctional centre where he will remain.
Turnbull will reappear in Moree Local Court on Tuesday, August 5.
Forensic officers continued to comb two crime scenes on Wednesday as they piece together the puzzle of what went wrong about 5.40pm on Tuesday.
Investigators believe Turnbull confronted officers on the remote laneway as they carried out their duties.
"It is alleged a 79-year-old man drove to the location, armed himself with a firearm and fired a number of shots before leaving," Barwon crime manager Detective Inspector Gavin Rattenbury said.
"Obviously it's a very difficult time for all those involved in the investigation, obviously for the family for the deceased and the community.
"Rest assured we're doing everything we can to investigate the matter and we'll continue to do so."
Police haven't ruled out laying further charges in relation to the incident.
