More than 100 police officers sent to remote NSW to capture an accused triple killer will remain there until he is found, NSW Police Commissioner Mal Lanyon says.

Lanyon vowed on Thursday to find the fugitive Julian Ingram, who remains on the run after allegedly fatally shooting three people, including his pregnant former partner Sophie Quinn and her aunt Nerida Quinn, in the western NSW town of Lake Cargelligo on January 22.

“I want to make sure that not only are you safe, but you feel safe,” Lanyon said.

“You will continue to see a significant policing presence until such time as we put Mr Ingram before the court.”

It came as NSW Police released footage of Ingram at a local police station on the same days as last Thursday’s triple shooting.

Police also said specialist riot squads would join the search, which has entered its second week, and all leads were being investigated.

Assistant Commissioner Andrew Holland said the latest sighting was of a rider on a red motorcycle but could not confirm it was Ingram.

Holland noted the getaway ute driven by 37-year-old Ingram could be hidden.

“He’d be mad if he was still using his original ute. But if he’s got other vehicles involved, we want to make sure we are investigating any lead that we have,” he said on Thursday.

Police have warned they will arrest and prosecute anyone who is helping the experienced council worker to get food and water, as a heatwave continues across the outback region.

The tricky terrain offering ample hiding spots between sheds and vast properties, some of which exceed 160 square kilometres in size, are posing challenges for officers.

“All members of the community should exercise extreme caution,” Holland said.

“They need to be aware that there is a gunman on the loose in their area. Again, we ask them not to approach this person.”

Meanwhile, the women’s friends and family have since asked the public for donations as the manhunt continues.

“Nerida and Sophie will be missed by so many,” family friend Leisa-Ann Kilby said online.

Quinn, 25, and her friend John Harris, 32, were killed when bullets were fired into a dark hatchback on Bokhara Street about 4.20pm.

Soon after, her aunt, 50, was shot dead at a home on Walker Street, a two-minute drive away.

A 19-year-old man was also shot at the home but survived. He remains in hospital in a serious but stable condition.

Suspicion and tensions are high as the search for the alleged triple killer enters a second week.

The sudden, massive police presence in Lake Cargelligo, which is home to only about 1000 people, has prompted authorities to reassure locals.

The possibility of Ingram having high-powered guns was likely to increase tension on remote farms and stations, police veteran and criminology academic Vincent Hurley said.

However, the targeted nature of his alleged killings should lessen the threat of more violence, Hurley said.

“The community could feel slightly reassured that he’s not after a random individual,” he said.

The openness of the terrain, particularly compared to the alpine country search for fellow fugitive Dezi Freeman in Victoria, should allow police to conduct a more thorough search for longer.

Lanyon said domestic and family violence remained a scourge on the community and its eradication was a personal focus.

“A tragedy like this brings domestic and family violence into the picture even more,” he said.

“We will work right across government to make sure all possible services [in the regions] are available.”
