It's been 14 years since Kayo Matsuzawa walked out of an Auckland backpackers to her death.
The 29-year-old was murdered just hours after she arrived in the city and her naked body dumped in an obscure utility cupboard in a warren-like CBD building.
The case was grisly and shocking. Despite that, public interest in the murder was never piqued, Kayo's plight faded into the background and her killer still walks free.
The body was discovered 14 years ago this Friday and despite police saying they have no new leads, they remain hopeful of solving the killing.
Detective Inspector Scott Beard, one of Auckland's top investigators and the district field crime manager, has been overseeing the file on Kayo's death. The investigation, named Operation Net, remains open and active.
"A senior detective has been responsible for reviewing the investigation and dealing with any new information that comes in to the police," Mr Beard told the Herald.
"To date there has been nothing to advance the investigation."
He would not be drawn on the suspect list, details of any profiling done around the killer or the specifics of the investigation to date.
Mr Beard reasoned that it was not the right time for police to release more detail than they already had about Kayo's death.
"If we had some information that I thought would warrant the use of the media I would do so," he said.
Kayo came to New Zealand from Japan in 1997 and settled in Christchurch for a year, studying English and working at a restaurant. In September 1998 she decided to travel north.
On September 11, 1998 Kayo flew to Auckland. At 2.14pm she was captured by CCTV cameras getting off a bus and crossing Queen St. The grainy images are the last of Kayo alive.
She checked into the Queen Street Backpackers, telling them she wanted to stay three nights. Then she walked up two flights of stairs to room 25, put her bags on her bed and headed outside again.
Ten days later her body was found in a locked fire-alarm cupboard of a stairwell linking the Centrecourt and BNZ buildings in Queen St. Kayo was naked and her body decomposing.
Police were never able to pin down how she died, but it was clear she had been murdered.
Police have never commented in detail on the state Kayo was found in, saying there are things only police and the killer would know. In 2000 Detective Inspector Kevin Baker, who was running Operation Net at the time, revealed police had collected forensic evidence from Kayo's body.
Those items, which he would not identify, had not been tested at the time. Police wanted to hold off, fearing they might jeopardise their chances of a DNA extraction in the future with better technology.
