THE State Government has offered a $250,000 reward for information on a murder in Mandurah in the 80s.

Annette Caroline Deverell was just 19 when she vanished on September 13, 1980.

Her body was discovered 22 months later in bushland off Scarp Road in Pinjarra.

The young woman’s murder has never been solved.

The Government this week announced a reward for information which leads to an arrest and conviction for Ms Deverell’s murder.

Further, the Government says it may consider protection or a pardon for anyone with information that leads to a conviction, provided the informant was not directly responsible for Ms Deverell’s death.

Ms Deverell was last seen alive at the corner of Mandurah Terrace and Pinjarra Road, near Mandurah Post Office about 11.30pm on September 13, 1980.

She was seen talking to a young man about 11pm.

That man has never been identified.

Police Minister Michelle Roberts this week described the murder as a “terrible crime” that continues to haunt the Mandurah community.

“I only hope that the offering of this significant reward might lead to the information that police need to solve the case,” Ms Roberts said.

“I want to thank local MP David Templeman for raising the case with me.

“When we both met Annette’s mother this week, we heard firsthand of the pain and anguish that 39 years of uncertainty has had on the family.

“Please, I urge anyone who knows what happened to Annette to come forward.”

Anyone with information is asked to contact Crime Stoppers on 1800 333 000 or report it online here.
