The Cold Case Homicide Squad is appealing to the public for information regarding the 2001 disappearance of then-23-year-old Rebecca Anne Delalande.
Detectives became aware of Ms Delalande’s disappearance in late 2017 as they conducted inquiries into an unrelated matter. Further inquiries with Ms Delalande’s family and friends revealed she had not been seen or in contact since November 2001. 
“Rebecca was a young mother who had a network of family and friends who cared for her,” Cold Case Homicide Squad Detective Senior Sergeant Craig Stephen said.
“She had infrequent contact with her family, and they had formed the belief that she had relocated to the Eastern States to establish a new life.
“We believe Rebecca was the victim of a serious crime and we are working hard to establish the circumstances surrounding her disappearance.”
Det-Sen. Sgt Stephen said Ms Delalande had challenges in her life, "but those challenges should not overshadow the fact that she was loved by her family and she may have become a victim of a serious offence."
“Someone in the community will know what happened to Rebecca and we appeal to them to come forward with information.”
Ms Delalande was described as 161cm tall with a slim build, brown hair and brown eyes. She attended a dental appointment on 5 November 2001, and was seen at a home on Fortunella Grove, Seville Grove, soon after that.
At the time of her disappearance Ms Delalande’s son was six-years-old and has been raised by other family members.
“News of Rebecca’s disappearance have obviously come as a shock to her family, and we are committed to finding answers for them,” Det-Sen. Sgt Stephen said.
Anyone with information regarding this matter is urged to contact Crime Stoppers on 1800 333 000 or by visiting www.crimestopperswa.gov.au, where information is confidential and rewards are available.
