Police have warned Lake Cargelligo and surrounds to use ‘extreme caution’ and are exploring whether Julian Ingram is receiving help to stay hidden

A gunman suspected of killing his pregnant former partner and two others in remote NSW remains on the run, as police revealed he reported to local officers as part of his bail conditions only hours before the shootings.

Julian Ingram, 37, was last seen driving out of Lake Cargelligo, in the NSW central west, on Thursday. Police suspect he is armed with at least one firearm, but confirmed he has never held a firearms licence.
