Police have confirmed Julian Ingram was seen on the side of a road two days after he allegedly murdered three people, and believe the accused triple-murderer is still receiving help from the public to evade capture.

NSW Police Assistant Commissioner Andrew Holland this afternoon said Ingram, also known as Julian Pierpoint, visited a property on Kidman Way, three kilometres south of Mt Hope, “in the dark hours of the night” between January 24 and 25.

He urged anyone with information about Ingram’s whereabouts to contact police.

The revelation comes after two women detailed a scary encounter with a man they believe was Ingram.

The 37-year-old is wanted over the Lake Cargelligo shooting deaths of his heavily pregnant ex-partner Sophie Quinn, 25, her friend John Harris, 32 and aunty Nerida Quinn, 50,as well as the serious injury of Kaleb Macqueen, 19, on January 22.

Police have battled what Holland described as “oppressive” conditions in western NSW, where temperatures have hovered above 40 degrees for days on end as their expansive search for the fugitive nudges two weeks.

Holland said he believes Ingram is receiving help from members of the public to remain unsighted by police.

“After 12 days in this heat and the conditions he’s in, I do believe he’s getting help and we’re appealing to the members of the public to give us some support,” he said.

Holland today called a level two critical incident investigation into the alleged triple murder, which will examine the police response, as well as Ingram’s domestic violence history and how he got access to guns before the shooting.

“Fresh information has come forward and it’s given me reason to believe that the matter needs to be further investigated, hence my reasoning for creating the critical incident investigation,” Holland said.

Police are continuing a large-scale search surrounding Lake Cargelligo, including support from the Police AirWing, Tactical Operations and the Rescue and Bomb Disposal crews.

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

“We do believe he’s still got access to the main vehicle he was using, we’re not sure which vehicle he is using at present,” Holland said.
