Police have released new images of a white ute as they hunt for a man accused of shooting three people dead in the NSW central west.

Julian Ingram, also known as Julian Pierpoint, is wanted for alleged murder.

Police said the 37-year-old was last seen driving a dual cab Ford Ranger utility with the NSW registration DM-07-GZ.

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.

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 is described as being Aboriginal/Torres Strait Islander appearance, about 165 centimetres to 170 centimetres tall, of a medium build with short dark hair and brown eyes.

Police said anyone who sees Ingram or the vehicle is urged not to approach but to contact triple zero immediately.

Ingram has been on the run since Thursday when three people were killed in Lake Cargelligo.

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 Sophie’s aunt Nerida Quinn, 50, was shot dead in the driveway.

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

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