Authorities believe the fugitive is still alive.

Three victims of Julian Ingram’s alleged shooting spree in NSW will be laid to rest this week as police offer a major reward for information leading to an arrest.

Funerals will be held for Sophie Quinn, 25, her unborn baby boy and her auntie Nerida Quinn, 50, on Thursday following their alleged murders in Lake Cargelligo on January 22.

They were allegedly shot dead by Ingram, 37, along with Sophie’s friend John Harris, 32.

A friend of Nerida’s son, 19-year-old Kaleb Macqueen, was also seriously injured in the alleged attack.

It’s been theorised Ingram had learnt he was not the father of his ex-partner Sophie’s unborn child, which may have triggered the alleged killing spree.

Police have also announced a $250,000 reward for information leading to the arrest Ingram, also known as Julian Pierpoint.

Ingram has not been sighted since the day of the crime despite extensive searches by police who have covered 60,000 acres in the area.

NSW Police Assistant Commissioner Andrew Holland said police do believe the alleged killer is still alive.

He has not used his phone or accessed his bank accounts in the almost seven weeks he has been on the run.

“There is still the belief that he is being supported by (someone) in the community, again seven weeks in the arid country and the arid land … he would have (had) to have support,” Holland said.

“When you look at the size and scale of the area involved, he could be … in the scrub land, he could cover the vehicle involved with tree branches. We don’t see it from the air, we won’t see it from the ground until someone gives us information hence why the rewards been offered.”

NSW Police Deputy Commissioner Paul Pisanos said the victim’s funerals marked a “significant milestone” in the case and hoped the reward would encourage those with information to come forward.

There will be police in the area leading up to, during and after the funerals on Thursday.

Pisanos said there was no specific information to suggest there was any risk to the community.

Ingram was last seen driving a Ford Ranger utility with NSW registration DM-07-GZ.

Neither his ute, or the gun used in the alleged crime, has been found.

Minister for Police and Counter-terrorism Yasmin Catley said Ingram’s alleged crime has “shattered” lives.

She said the smallest piece of information could make all the difference.

“We believe that you can help us,” Catley said.

“We believe that there is somebody out there that can helps us find Julian Ingram and give this community and these families piece of mind.”

Ingram is described as being of Aboriginal/Torres Strait Islander in appearance, about 165cm-170cm tall, of a medium build with short dark hair and brown eyes.

The ute he was last seen driving had council signage on it, a metal tray back, high visibility markings on the side and an emergency light bar on the roof.

Anyone who has any information has been urged to contact Crime Stoppers.
