On 18 June 2013, Ms Carlie Sinclair went missing from her business premises in Parap.
The subject of a Major Crime investigation, a special investigation unit “Operation Samburu,” have been dedicated to this case.
To mark one year since her disappearance and assist NT Police with investigations, Crime Stoppers NT launched a wide-scale campaign to help reinvigorate the case and call for public information.
Crime Stoppers NT asked Territorians "What happened to Carlie Sinclair? What happened to Alex’s mum?"
Eighteen months following her disappearance, information obtained from the public, through Crime Stoppers and the Police Information Line, has led to a significant breakthrough.
NT Police Commissioner, John McRoberts said a body, believed to be Ms Sinclair's, had been found at Berry Springs, in Darwin's rural area and a man in custody.
Mr McRoberts described the arrest as a significant development.
"As a result of a man being seen in the Berry Springs area, he has been arrested and we are now holding him in custody until the results are known of a comprehensive crime scene analysis which is currently underway," Mr McRoberts said.
“Based on all the evidence that has been compiled, based on the fact that we now have a man in custody, based on the fact that we now have what is clearly a gravesite at Berry Springs, we are very confident that we have solved the mystery surrounding the disappearance of Ms Sinclair," he said.
Along with Carlie’s family, the dedicated team of detectives that have been working on this case since the outset are delighted that a breakthrough has occurred to bring justice for Carlie.
