South Australian Police are urging the public to come forward with crucial information they believe is being withheld regarding the unsolved murders of a mother and her daughter. This plea follows the conclusion of the latest investigation related to these tragic events.

Rosemary Brown, aged 33, and her 15-year-old daughter, Melissa Trussell, were last seen in the early hours of May 13, 2000, in Blair Athol, a suburb in northern Adelaide.

Authorities suspect that Brown was murdered, and they believe that Trussell likely met the same fate, although her remains have never been located.

Brown’s body was tragically discovered in the mangroves of Garden Island, Adelaide, on July 2, 2000.

Detective Superintendent Darren Fielke addressed the media today, emphasizing that officers are convinced some individuals are withholding key information.

“We are aware that there are people who possess vital details but have yet to come forward or assist the police,” he stated.

“This is the murder of a mother and her 15-year-old daughter. The remains of Melissa have not been found.

“Put yourselves in the shoes of the family of Rosemary and Melissa – they want answers about what happened to their loved ones and to recover Melissa’s remains.

“Your information may be the missing piece of the puzzle that leads to the family getting the answers they deserve.”

Detective Superintendent Fielke said detectives have identified “several suspects” and have searched two homes connected with one.

But they believe more than one person was involved in the murders and disposal of the bodies.

“To those who played a minor role, or who may have found themselves in a situation they couldn’t remove themselves from – now is the time to come forward and tell your story,” he said.

A knife has also been found, with DNA testing being done.

A million dollar reward is on offer leading to a conviction over the suspected murder of Melissa Trussell and $20,000 over that of Rosemary Brown.
