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

Police have released new images of a vehicle linked to accused killer Julian Ingram in NSW’s Central West as officers intensify a large-scale search for the fugitive.

The 37-year-old is wanted in connection to the shooting death of his pregnant ex-partner, Sophie Quinn, 25, her friend John Harris, 32, and her aunty Nerida Quinn, 50, in Lake Cargelligo last Thursday.

Ingram has been on the run ever since, with more than 100 police involved in the ongoing search.

He was last seen driving a dual-cab Ford Ranger ute with NSW registration DM-07-GZ.

Police released additional images of the vehicle on Tuesday, following the release of two earlier photos on Saturday.

“The vehicle may have a Lachlan Shire Council magnet in front of the driver’s door and may have the numbers 1947 above the magnet,” NSW Police said in a statement.

“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.”

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.

Residents in the region have been left on edge as the manhunt continues.

A warning has been shared on a local community page after two separate groups reported encountering a white ute allegedly driving aggressively near Murrin Bridge, a former Aboriginal mission home to fewer than 100 people.

Police allege Ingram fatally shot Quinn and Harris while they were inside Quinn’s black Suzuki Swift on Bokhara St about 4.30pm.

A short time later, police said he drove just a few minutes to Walker St and opened fire in the driveway, killing Nerida and seriously injuring 19-year-old Kaleb MacQueen, a friend of her son.

MacQueen was airlifted to Canberra and told 7NEWS he has been suffering “a lot of pain” to his shoulder, hands and the back of his head.

He alleged Ingram was laughing as he fired the shots.

“I heard boom, boom. She was, yeah, holding her neck and then he was laughing.” he said.

MacQueen and his mother, Jessica Johnson, said they have been left fearful knowing Ingram remains at large.

“I feel like he’s going to come,” MacQueen said.

The pair are pleading with police to find Ingram, saying they won’t feel safe until he’s caught.

Police said they are continuing to assess reports of possible sightings of Ingram as they are received.

“Police encourage the community to continue to use 131 444 to report any information that may be useful to the investigation,” NSW Police said.
