Julian Ingram, a 37-year-old triple murder suspect, remains at large one week after allegedly shooting dead his ex-girlfriend Sophie Quinn, John Harris, and Sophie's aunt Nerrida Quinn in Lake Cargelligo in the state's central west. Police Commissioner Mal Lanyon has visited the area to support the large team of officers battling extreme 40-plus degree temperatures and rough terrain in their search. Extra riot squad officers are being deployed over the weekend to maintain a significant police presence at planned community events until Ingram is apprehended.
