She was last seen leaving the home of the Euroka Street family around 6 pm on Saturday, June 5, 1982. Her body was never found.
The renewed investigation into the disappearance and alleged murder of Mrs. Bowie is being led by the theft and squad of felonies from the State Crime Command under the Maluka Strike Force.
Earlier this month, Detective Superintendent Daniel Doherty said the police would never give up the investigation.
"Roxlyn Bowie was described as a calm and shy woman, and a beloved daughter and mother," said Detective Doherty.
"Of all the accounts, Mrs. Bowie was completely dedicated to her two small children, which makes her disappearance very disconcerting for those who knew her well."
During the investigation, the attorney who assisted Judge Sergeant Paul Bush said that Mrs. Bowie had planned a party for her son's second birthday before he disappeared.
His daughter Brenda, who was six years old when her mother disappeared, told the investigation that her mother was "the most affectionate" and remembered having baked cakes with her.
Roxlyn's husband, John Bowie, also spoke in the investigation, and was open about his own behavior, including drinking and extramarital affairs. He also admitted falsifying his wife's signature on a land transfer document in 1984.
Coroner Mary Jerram said she "gave very little weight" to some of her tests, but letters to her husband and her parents announcing their intention to leave remain "an obstacle."
