Twist as new photo emerges after model's mysterious disappearance

A photo could help solve the mysterious disappearance of a model who vanished more than 26 years ago.

Revelle Balmain went missing when she was 22 years old from the Kingsford area in Sydney's east on November 5, 1994.

Her make-up bag, keys and a shoe were found scattered near Ainslie Street but she has never been seen or heard from since and despite investigations from police, nobody has been charged.

However, now NSW Police have released an image of a man they believe may have information about Ms Balmain's last movements before her disappearance.

NSW Police Detective Chief Inspector Stuart Bell said in a statement the photo was sent to them anonymously after they announced in May a $1 million reward in exchange for information that leads to a conviction.

"It is believed that this image was taken some time in the mid-2000s, but that the individual depicted may have information that would help us progress our investigation," Det Ch Insp Bell said.

"It is our hope that someone in the community may recognise this man so we can speak with him and ensure all possible avenues of inquiry are followed through.

"As always, we continue to encourage anyone in the public that may have information about Revelle's disappearance to come forward and speak with police, so that we may finally provide answers to her family."

Sister's heartbreak after disappearance

Revelle’s sister, Suellen Simpson, said earlier this year the disappearance had caused immeasurable grief to her family.

“For many years, our family worked tirelessly to find out what happened to my sister – but sadly both our mother and Revelle’s father, Ivor, passed away without ever knowing what happened to their little girl,” Ms Simpson said.

“Losing someone that is close to you – you’re never the same person again."

Despite Ms Balmain's disappearance remaining a mystery for more than two decades, a coronial inquest in 1999 found that the model had died at the hands of a person or persons unknown.

The case was referred to the Unsolved Homicide Unit for future investigation.

Anybody with information is urged to call Crime Stoppers on 1800 333 000 or submit an anonymous report online.
