Police have released images of clothing worn a woman found dead in a Blue Mountains dam in a bid to solve her disappearance and murder.

Cecilia Devine’s body was found at the Upper Cascade Creek dam by staff at a water treatment facility in Katoomba in March this year.

The 42-year-old had been reported missing from Waratah on Wednesday 5 September 2018.

CCTV footage of Ms Devine released earlier this year showed her walking from a hotel in Katoomba Street, Katoomba, on September 6 wearing a distinctive bright yellow cardigan and black pants, and carrying an orange handbag, none of which have been recovered.

Police have released images of similar clothing in the hope that someone may remember seeing them, or Ms Devine, in the area at the time.

“We’ve established some strong leads into Cecilia Devine’s disappearance and death in recent months but there are still many unanswered questions,” Detective Sergeant James Allan said.

“We are confident that there are people in the community who have information but have been reluctant to contact police and tell us what they know.”

Anyone with information is urged to contact Crime Stoppers.
