Heather Marks was on her way to Leichhardt Pool in Sydney’s Inner West when she vanished without a trace more than 40 years ago.

Marks, then aged 53, was seen walking towards the pool on Glover Street in Rozelle, about 9.30am on Wednesday 13 April 1983. 

Her family never saw or heard from her again.

Police are appealing for the public’s help to find Marks, as part of this year’s ‘Forever Loved’ Missing Persons Week 2025.

In August 2008, the NSW Deputy State Coroner declared Heather was dead, but no finding was made regarding her manner or cause of death.

The ruling has not stopped Marks’ family searching for answers.

At the time Heather vanished, it is believed she had a partner named ‘Ray’, who, according to her family, worked as an interstate truck driver traveling between Sydney and Melbourne.

Heather’s granddaughter, Natalie Jackson, is making an appeal to Ray or anyone who might have information about him or her grandmother’s disappearance to come forward.

“We are really hopeful that with time passing, someone out there might feel more at ease to help us discover what truly happened to our grandmother,” Jackson expressed.

“My mum has lost all of her siblings – she is the last one left – and I am desperate to get these answers for her.

“To everyone else my grandmother is a missing person, but to us she is just really missed.”

Marks was about 165cm to 170cm tall. She had grey hair and blue eyes.

She also lived with a number of medical conditions.

Minister for Police and Counter-terrorism, Yasmin Catley said Heather Marks’ disappearance showed the toll of missing persons cases on families.

“It’s been over 40 years since Heather Marks was last seen, yet her family’s pain and unanswered questions are just as intense today as they were in 1983,” said Catley.

“No family deserves to remain in the dark for four decades. If you know anything, even if it seems minor, please reach out to Crime Stoppers and help bring some closure to Heather’s family.”

Assistant Commissioner Scott Cook of the State Crime Command noted that Missing Person’s Week provides an opportunity for the police to bring long-term missing individuals back into public awareness and continue the pursuit of answers.

“In New South Wales, around 10,000 people go missing every year and sadly, some are never found. As Missing Persons Week begins, we stand in solidarity with those still searching for loved ones, and we acknowledge the deep pain carried by families and communities affected by these long-term cases.

“As we continue our investigations, we urge anyone with information, no matter how minor it may seem, about Heather Marks or any long-term missing person to come forward. Even the smallest detail could help bring closure to a family who has waited decades,” Cook said.
