Diamond ring could hold clues to 1982 disappearance of Roxlyn Bowie
A diamond ring that once belonged to a woman who has been missing since 1982 from the state's north-west could hold clues to her disappearance, police say.
Police have released images of the ring, hoping the buyer has information that could help their investigation into Roxlyn Bowie's suspected murder.
Ms Bowie was reported missing after she was last seen leaving the Walgett home she shared with her husband and two children about 6pm on Saturday June 5, 1982. She was aged 31 at the time.
In September 2014, a Coronial Inquest found Ms Bowie had died on or around the date of her disappearance. While the inquest found it was "highly likely" she had been killed, the cause of death was undetermined.
Last year detectives from the state crime command's robbery and serious crime squad launched a renewed investigation into her disappearance with Strike Force Maluka.
On Wednesday, investigators released photographs of a diamond ring similar to one that was bought from a Bankstown pawn shop on Wednesday June 6, 1984.
Detectives believe the ring once belonged to Ms Bowie, but despite numerous searches they have not found it.
Strike force detectives also conducted more forensic tests at Ms Bowie's home on Tuesday evening.
It follows November's forensic examination of two sites not far from Ms Bowie's home in the search for her body, which has not been found.
Officers searched and dug up a dam in Walgett and also examined a nearby industrial site in a search that was expected to take three weeks.
At the time, robbery and serious crime squad commander, Superintendent Daniel Doherty said he was "hopeful" they would find clues to Ms Bowie's disappearance.
"Ultimately, what we'd like to find is evidence that may lead us to the location of Roxlyn's body," he said.
"It's been 36 years since Roxlyn disappeared, and that's a long time for [Ms Bowie's daughter] Brenda and her family to not know the truth of what happened."
Strike Force Maluka investigators targeted the dam and industrial site after receiving information from the public.
Detectives are appealing for anyone with information about the ring to contact Crime Stoppers.
