The “very decomposed” body found in the search for Julian Ingram is set to undergo testing to confirm it is the accused triple killer.

Police said that the remains have been removed from a remote NSW national park where they were found yesterday and will undergo post-mortem testing on Friday in Newcastle, before confirming it is Ingram.

National Parks and Wildlife staff made the discovery in Central West NSW, four months after Ingram allegedly murdered his heavily pregnant ex-partner Sophie Quinn, 25, her friend John Harris, 32, and aunt Nerida Quinn, 50, in Lake Cargelligo.

Assistant Commissioner Andrew Holland said a vehicle and a firearm were also set to be forensically tested.

“There was a firearm located next to the deceased body, which was a large calibre firearm and a shotgun located on the front passenger seat of the vehicle,” he said.

“It would appear that the deceased was dressed in the same clothing he was wearing on the day of the incident, assuming that it was Julian Ingram.

“The injuries appear self-inflicted with a firearm.”

The body was found next to the white Ford Ranger Ingram was last seen fleeing the town in, and his licence was inside the vehicle.

When asked if Ingram potentially received help from somebody in the community, Holland said, “It does not appear to be the case”.

The update from police comes as new aerial footage revealed the bushland location where a white ute was found in relation to the manhunt for the accused triple killer.

Lake Cargelligo community reacts to the grim discovery

Loved ones were rocked by the discovery but said they could finally grieve.

Assistant Commissioner Andrew Holland yesterday said the discovery was a relief for officers who’d been involved in a major manhunt for the accused killer, but particularly for the affected families.

“For the last four months, the strike forces involved in … the manhunt for Julian Ingram, have not given up,” he said.

“There’s been hundreds of police involved.

“Obviously, it’s a relief for them to find this body – again, yet to be confirmed as Julian Ingram – but the main thing is, it brings closure to this investigation, it brings closure to the people of Lake Cargelligo and gives some solace to the town so they can relax.”

While police had not officially confirmed the body was Ingram, they do believe it is him. The corpse was found in his clothes next to the white Ford Ranger he was last seen fleeing the town in, and his license was inside the vehicle.

Holland said the body was found in a “very decomposed” state but didn’t give a specific estimate for when the man may have died, saying only it “appears to have been there for some time”.

He did not confirm whether the weapon was the same alleged to have been used in the shooting or whether the man was believed to have died by suicide.

Police said NPWS workers carrying out feral animal eradication found the vehicle about 3.40pm yesterday in Round Hill Nature Reserve, roughly 100 kilometres north-east of Lake Cargelligo.

Ingram, 37, had been on the run since the January 22 shooting.

He allegedly killed his pregnant former partner, Sophie Quinn, and her friend John Harris, then moving on to Sophie’s Auntie Nerida, killing her and shooting Kaleb Macqueen, 19, the only victim to survive.

“I heard boom, boom. I seen her – she was holding her neck, and then he was laughing,” Macqueen told 9News in January.

Sophie’s mother, Cathy Quinn, called Ingram “gutless”.

“We still grieving but justice will be served,” she told 9News.

Her sister, Tegan, said it was “about time they found him”.

“We can grieve but now it feels so real and it’s only has hit me now,” she said.

The shooting devastated the tiny town and rattled the entire state.

Last month, police said Ingram was seen on the side of a road two days after the alleged murders.

In March, police offered a $250,000 reward for information leading to his arrest.

The coroner will now be charged with confirming how the man died and when.

If the body is confirmed to be Ingram, everything leading up to the killing will also be investigated, including why the repeated domestic violence offender was out on bail.
