Homicide detectives say a woman whose body was wrapped in plastic and dumped in a creek near Lake Macquarie was never reported as missing.
The remains of 29-year-old Danielle Easey were found in Cockle Creek at Killingworth on Saturday.
An autopsy is expected to be carried out in an attempt to reveal how and when she died, but it is believed her body may have been dumped in the creek a long time ago.
Ms Easey lived in the suburb of Booragul with family, but had also been staying at multiple locations in the area.
Motorists found the body at around 10.30am on Saturday as they drove through isolated bushland along Wakefield Road.
A crime scene was established at the creek and some roads were blocked off as emergency services scoured the area for clues to reveal what may have happened.
Police have not given any formal statement about the condition of the woman’s body, but officers are treating the death as suspicious.
A source close to the investigation said CCTV had been gathered from homes and businesses around the Barnsley area.
Anyone with information should contact Crime Stoppers.
