WARNING: Aboriginal and Torres Strait Islander readers are advised this story contains images of people who have died

A gunman who allegedly fatally shot three people had been subjected to multiple apprehended violence orders from five different people over the last decade as police continue to track down the fugitive.

Police have released the images on the third day of the search efforts for 37-year-old Julian Ingram, who police allege is responsible for the deaths of three people and the serious injury of another in Lake Cargelligo, western NSW, on Thursday.

He is believed to be driving a dual cab Ford Ranger with NSW registration DM-07-GZ, with a magnet in front of the driver’s door with the Lachlan Shire Council logo and four black numbers above it.

“The ute also has an emergency orange light bar on the roof and the utility’s tray may contain work tools and a silver toolbox,” police said.

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

Anyone who sees Ingram or the vehicle has been urged not to approach him and to contact emergency services immediately.

“I think everyone needs to be concerned for their safety at this point,” NSW Police Assistant Commissioner Andrew Holland said on Saturday.

Police believe he killed his 25-year-old pregnant ex-partner Sophie Quinn and her new boyfriend, 32-year-old John Harris, on Bokhara St on Thursday afternoon.

Police allege that a short time later, 50-year-old Nerida Quinn was fatally shot in the driveway of a home on nearby Walker St, while 19-year-old Kaleb MacQueen was shot and seriously injured.

Holland said Ingram is known to the victims and it is “definitely a domestic relationship”.

He confirmed Ingram had been on bail since November when he was charged with stalking or intimidating, common assault, and damaging property and an apprehended violence order (AVO) was in place.

Police never opposed Ingram’s Bail, when it was granted by a magistrate last year.

Ingram undertook a risk assessment last week and has always complied with his conditions, police say.

Court records obtained by 7NEWS have revealed Ingram has been subjected to six AVOs since 2014, protecting five people, including Quinn.

Part of his bail conditions was to report to police at the Lake Cargelligo Police Station, doing so just eight hours before allegedly opening fire on Quinn and three others.

The last sighting of Ingram, a council gardener, was on a road heading out of town and more than 100 police officers are involved in the search for him.

“We’ve only had one sighting of him, that was the day of the incident and that was him leaving Lake Cargelligo,” Holland said.

“This offender, we can’t tell what his actions are going to be in the future, what he’s going to do next.”

Police on Saturday widened the search area by about 30 kilometres to Euabalong – raiding two properties so far.

“There is the possibility that people are assisting him to obviously avoid police apprehension,” Holland said.

The search has focused on sheds and rural properties where he could be hiding.

Holland said “there is police on almost every corner of Lake Cargelligo at the moment” but reiterated there is no lockdown and people can move around as they need to.

Holland said Ingram, a council gardener, knows the local area well, and “it is feasible that he could maintain an extended period in the local area without being detected”.

Witness Zac Phillips who knows Ingram said the fugitive “knows this place like the back of his hand”.

“He can disappear and reappear whenever he wants.”

He added the alleged shooting was unexpected.

“He was doing really well for himself you know he had a pretty rough life and a few rough things happened in his past and stuff like that, but he started doing well for himself,” he said.

Police say it is unclear how the firearm was obtained and confirmed the man does not hold a firearms licence.

Holland described the incident as “a tragedy in a small community”.
