Tactical police are searching a property in the Mount Hope area this morning as the search for accused killer Julian Ingram continues in New South Wales.

A reported sighting on the weekend drew police focus to the district, after Ingram allegedly killed three people and went on the run in Lake Cargelligo last week.

NSW Police Assistant Commissioner Andy Holland said investigators had a number of properties under observation, and were searching one of them this morning.

Holland said it was currently believed Ingram was acting alone, though he could not rule out the possibility he was receiving aid from a member of the community.

“We are talking to (Ingram’s) associates,” he said.

Police weren’t sure if Ingram was still carrying a gun, he said, but he urged the public to consider him armed and dangerous.

Locals at Mount Hope are not in lockdown but are advised to remain on high alert, while visitors and campers in the area have been urged to leave.

Holland said the search would continue at its current level of intensity for “a number of days”, despite officers facing temperatures in the mid-40 degree range.

“The heat will not stop the search of those locations by police,” he said, despite admitting conditions were “not ideal”.

Ingram, 37, is accused of shooting three people dead at two locations in Lake Cargelligo on Thursday afternoon.

Two of them, his pregnant ex-partner Sophie Quinn, 25, and her friend John Harris, 32, were shot dead in their car.

Ingram is then believed to have travelled to a second address where Quinn’s aunt Nerida Quinn, 50, was shot dead in the driveway.

Kaleb Macqueen, 19, was injured in the same shooting.

Sophie Quinn, who was due to give birth in March, separated from Ingram last year.
