Chilling missing persons cases haunting Brisbane
The chilling stories of the last movements of a select few men and women continue to haunt Brisbane, even decades after they seemingly vanished into thin air.
According to the Australian Federal Police Missing Persons, more than 38,000 people are reported missing each year.
While most people are found, some 2,600 people have been listed as long term missing person - missing for more than three months.
In Queensland, 59 people remain on that list - 18 missing from Greater Brisbane.
Here are the stories of some Brisbane's most chilling missing persons cases.
Caboolture: Sandrine Jourdan
Sandrine Jourdan was 37 when she vanished from Caboolture on July 13, 2012.
She was last seen at a Caboolture home wearing a light mauve long sleeve jumper and dark dress pants.
For years her family members have been dogged in their search for the mother and while she remains a registered missing person, a coroner said it was possible Ms Jourdan - who had a history of drug use and mental health issues - had either been murdered or taken her own life.
Three people were questioned over the case, but none were ever declared a person of interest.
Redcliffe: Carolyn Stokes
Carolyn Stokes had simply gone for an afternoon walk on March 11, 2008 but she never returned.
The 58-year-old grandmother was last seen by her husband about 5pm.

An extensive search including police, a dog squad. State Emergency Service volunteers and a rescue helicopter were unable to find Mr Newbon.
Less than a year after Mr Newbon's disappearance, his wife Maureen said she was struggling to come to terms with the loss.
"I knew in my heart, the next day, he was gone," Mrs Newbon said. It just gives me the horrors and I find it difficult to come to terms with," she said.
Police combed scrub through Bribie Island for a trace of Mr Newbon as part of a large-scale search however nothing was found.

The vanishing was made all the more eerie when police confirmed none of Mr Goldsmith's belongings were missing - his car remained secure in its garage.
Reports of the tree surgeon's whereabouts - one alleged sighting in Normanton and another that he had been murdered and his body dumped in the Brisbane River - also failed to uncover anything.

Ms Smith's brother Bill said it was unlike his sister to disappear without contact.
