NSW Police have confirmed a body found in the state’s outback was Lake Cargelligo triple-murderer Julian Ingram.

His body was found beside his ute in the state’s central west about 3.30pm on Monday.

“The body has since been formally identified as 37-year-old Julian Ingram,” police said in a statement.

Ingram shot dead his pregnant ex-partner Sophie Quinn, 25, her friend John Harris, 32, and her aunt Nerida Quinn in a shocking shooting spree in the tiny rural town on January 22.

He fled the town and a massive manhunt failed to find any trace of him till Monday.

His body was found on Monday after the National Parks and Wildlife Service found an abandoned vehicle at Roundhill Nature Reserve about 100km northwest of Lake Cargelligo.

On arrival, police located the body of a man, and a crime scene was established before being forensically examined.

The vehicle and firearms were also seized for further examination.

Investigations under Strike Force Doberta remain ongoing and a report will be prepared for the coroner.

Ms Quinn’s relative said on Monday Ingram’s death didn’t bring justice to their family.

“It doesn’t bring them back,” they told the ABC.

“Justice doesn’t coincide with stolen lives.”

Sophie’s mother, Cathy, told 9News the alleged murderer was “gutless”.

Her sister Tegan said “it was about time (police) found him”.

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

On Monday, Assistant Commissioner Andrew Holland said a post-mortem would be carried out at New Parson on Friday.

He said the vehicle found at the scene was taken to Orange for forensic examination, with ballistic testing to follow on multiple weapons recovered.

“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,” he added.

Mr Holland said Ingram had not been sighted since fleeing, despite an extensive and prolonged operation since January 22.

“We’ve had over 300 intelligence reports coming from members of the public advising us with information about this matter,” he said.

“Each one of those has been investigated thoroughly.”

At this stage, investigators said there was no evidence Ingram received assistance while on the run.
