Queries raised in cold case

Shae Deverell, 24, said she hoped Australian Community Media's new podcast Annette: Cold Case Unlocked would encourage people to come forward with information.

The four-part series explores the mysterious death of Mandurah girl Annette Deverell and the dark secrets and suspicions that have haunted the community for decades.

Episode two, Who was Annette Deverell?, is now available on your favourite podcast app.

In this episode, we delve deeper into the mystery and get to know Annette.

Shae's father is Annette's brother Michael. The mother-of-one never got to meet her aunt, who died before she was born, but said her death impacted the whole family.

"I really wish I got to meet her," she said. "I wish she was still around so she could see us all grow up."

Annette would have nine nephews and nieces and many more cousins if she was alive.

Shae said she was "angry" there had never been a reward offered by the state government for information about Annette's death.

"I think we'll get answers if there is," she said.

"I also think the police could do a much better job than they did last time. We need justice, we want answers and we want to know. I hope they're alive to face the consequences - it makes me sick."

Shae said she thinks someone local was responsible for Annette's death.

"It could have been one of her mates at the time," she said. "She wouldn't hop into a stranger's car.

"You never know, our family could still be talking to them, standing around them and we don't know. She would have known the person."

The terrain where Annette Deverell's remains were found, in the bush just out of town, was hilly with dense jarrah forrest.

In the 1970s and 80s, Mandurah locals would chuck a keg in the ute before heading to the hills near Pinjarra and Dwellingup for a Sunday drinking session.

They would swim in the nearby dams and the boys would go hunting for rabbits. Some even grew their marijuana there.

They knew how to navigate the smaller bush tracks.

Annette's temporary resting place was in these hills, about a 30 minute drive from where she was last seen in Mandurah, near the Post Office, on September 13 1980.

Many people close to Annette believe someone local is responsible for her death, including her mother Margaret.

She said Annette must have known her "killer".
