"Everybody's on edge while the suspect is still at large," said John Medcalf, mayor of Lachlan Shire Council which includes Lake Cargelligo. "If he came onto a property and shot someone ... then it could take the ambulance half an hour to get there," Dr Hurley told AAP. "The community could feel slightly reassured that he's not after a random individual," Dr Hurley said. "It's feasible that (the search) could be six weeks," Dr Hurley said.
