The teenager who escaped with his life after alleged being shot by Julian Ingram has described the moment he saw his friend’s mother gunned down.

The teenager who survived after being allegedly shot by Julian Ingram has described the moment he saw the alleged triple killer laugh as he opened fire.

Ingram has been on the run from authorities for four days and is wanted after three people – including his ex-partner Sophie Quinn – were fatally shot in Lake Cargelligo on Thursday afternoon.

Ms Quinn, 25, and her friend John Harris, 32, were found dead with gunshot wounds inside a car.

Sophie’s aunt Nerida Quinn was also shot dead the same day while 19-year-old Kaleb Macqueen was seriously injured.

Mr Macqueen on Sunday told Nine News that he saw Ingram drive up to the home of Nerida Quinn, his friend’s mother, before opening fire.

“She’s obviously went towards the ute,” Mr Macqueen told Nine News.

“I heard boom boom … she was holding her neck and he was laughing and gave her one good shot to the head and she was gone.”

He said there was nothing he could have done to save Ms Quinn.

“I seen him point the gun out the window, and within seconds it was just too late… I had to save myself,” Mr Macqueen said.

“Not that I could have done anything with Nerida. I probably would have ended up dying if I went over to Nerida as well.”

He suffered injuries to his head, arm, shoulder and leg and has suffered nightmares since.

Police on Sunday said that Ingram had possibly been sighted in Mount Hope, an hour north of Lake Cargelligo.

“We now have a possible sighting of the offender in the Mount Hope district,” NSW Police Assistant Commissioner Andrew Holland said.

Commander Holland said the sighting was reported by members of the public in the early hours of Sunday, who identified “what they believed to be the offender”.

“It was a possible sighting. There’s no confirmation that it is the offender … but we are treating it as such,” he said.

“Police are in that location now carrying out searches of multiple properties in the area.

“Obviously with an armed offender in that area, we are asking for members of the public to exercise extreme caution.”

Assistant Commissioner Holland said CCTV footage has identified the alleged offenders vehicle, a white, single cab Ford Ranger with the number plate DM0 7GZ.

“If anyone has information related to this vehicle, could they contact triple-0 or Crime Stoppers immediately. We are seeking where this vehicle is immediately,” he said.

Police also announced Ingram is believed to be “on his own at this present time”.

“But again, we can’t rule out the possibility that he’s being assisted by others,” Assistant Commissioner Holland said.

Police confirmed they still believe Ingram remains in the Lake Cargelligo surroundings.

“We have the information on the vehicle … it’s been given to all high patrol vehicle so they can track the vehicle in the recordings,” he said.

“No one has reported that they’ve seen the vehicle leaving the district or other reports outside this area. So we believe, at this stage, to be still in the surrounds of Lake Cargelligo,” he said.

It is understood Ms Quinn had a previous relationship with Mr Ingram with police treating the deaths as an alleged domestic violence incident.

Ingram had previously been charged in relation to an alleged offence on November 12.

Court documents show that Ms Quinn had an apprehended domestic violence order (ADVO) taken out against him in December.

Ingram was charged with stalking or intimidating intending to cause physical harm and assault.

He pleaded not guilty to the charges and was due to face Lake Cargelligo Local Court on February 3.
