McGowan Government escalates Mandurah murder case with reward

WA Police is calling for help to solve a 39-year-old cold murder case, with the McGowan Government offering a reward for public assistance.

The government has offered $250,000 for information which leads to the apprehension and conviction of those responsible for the death of Annette Caroline Deverell in Mandurah.

Local Government Minister David Templeman had brought the case to Police Minister Michelle Roberts, escalating the government’s interest in solving the case.

Ms Deverell 19-years-old when she disappeared from Mandurah on December 13 1980.

She was last seen alive on the corner of Mandurah Terrace and Pinjarra Road, near the Mandurah Post Office at around 11:30pm that evening.

Ms Deverell was seen talking to a young man at around 11pm on the night of her disappearance.

The man nor the people responsible for Ms Deverell’s murder have never been identified.

Her remains were found 22 months later in bushland just off Scarp Road in Pinjarra.

State Cabinet approved the reward this week which they hope produce information.

The State Government said it may be prepared to consider recommending a protection from prosecution or pardon for any informant possessing information that leads to the conviction of those responsible for the death.

They would need to not be directly responsible for Ms Deverell’s death.

Mrs Roberts said the crime” still haunts” the Mandurah community, with hopes the reward will help close the case.

“This was a terrible crime,” Mrs Roberts said.

“I only hope that the offering of this significant reward might lead to the information that Police need to solve the case.”

She said she had spoken to Ms Deverell’s family and talked about the pain suffered by the loss.

“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,” Mrs Roberts said.

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

Anyone who has information about Ms Deverell’s death is encouraged to contact Crime Stoppers on 1800 333 000 or make a report online at
