Diamond Ring May Be Missing Clue Into Disappearance Of Roxlyn Bowie

A diamond ring may hold the clue into the disappearance of an NSW woman almost 37 years ago.

Roxlyn Bowie was 31-years-old when she disappeared from her northern NSW home in 1982, but despite a Coronial Inquest finding it was "highly likely" she had met with "foul play", her body has never been found.

Police now believe a missing diamond ring may be the missing clue into her disappearance.

Bowie -- described as a "shy and quiet woman", a devoted mother and daughter -- has not been seen for almost 37 years. She disappeared from her Walgett home on June 5, 1982, leaving her two young children sleeping in their beds, and the lights, heater and television on.

Detectives from Strike Force Maluka are now appealing to the public for information regarding a diamond ring believed to have belonged to Bowie, which was purchased from a Bankstown pawn shop the day after she went missing.

"Despite numerous searches, the ring has not been located," police said.

They have released images of a diamond ring similar to the one they're looking for, and are hoping its recovery will, at last, lead them to Bowie's body.

It comes after detectives and special forensic officers conducted further forensic testing at a home in Walgett on Tuesday.

Last year, police underwent a dig at two sites, one just metres from Bowie's family home. They also used ground penetrating radars to try and uncover any buried evidence from an old industrial site, where concrete slabs were laid at the time of her disappearance.

Bowie's daughter Brenda, who was six when her mother disappeared, said it's been hard living without knowing what happened.

"From what I remember of my mum, it just seems impossible that she would have left my brother or I, and I just ask that if any of the public can put themselves in my position, I just want answers," Brenda said last year.
