The remains of nine women have been found at a Canadian pig farm owned by a man accused of being a serial killer.
Police conducted a detailed search of Pickton's farm
Robert Pickton has already been charged with murdering 22 women, most of whom were linked to Vancouver's sex trade.
The 53-year-old has been in custody since his arrest in February 2002 - his farm searched for the last 18 months.
Police confirmed the discovery of nine more bodies on the farm, and added that they had so far been unable to identify three of the women.
"We believe that these DNA profiles belong to women who are missing but not yet reported missing to police," said Vancouver police spokeswoman Sheila Sullivan.
The other six were on a list of more than 60 prostitutes who have disappeared from the Vancouver area over the past two decades, she added.
Nearly all the women whose remains have been found were linked to prostitution and drugs in Vancouver's poor downtown eastside neighbourhood.
They vanished over a period of 25 years.
Police formed a task force to investigate the disappearances three years ago.
They have been criticised by relatives of the dead or missing for not taking their concerns seriously.
Investigators have spent nearly two years searching Mr Pickton's farm near Vancouver, pulling down buildings brick by brick and sifting through tons of soil and debris.
No trial date has been set. Preliminary hearings are expected to begin in September.
If found guilty, Mr Pickton would be Canada's worst serial killer.
