Robert Pickton, a Vancouver pig farmer accused of being a serial killer, has told police that he murdered 49 women.
Prosecutor Darrell Previtt on Monday told jurors at the trial in a Vancouver courtroom that Pickton was plotting to kill a 50th woman before "shutting it down", Canadian media reports said.
Previtt told jurors that when the police descended on Pickton's suburban pig farm with a firearms search warrant, they found a gruesome scene, including the severed heads of two victims in plastic buckets inside freezers.
Pickton is charged with the first-degree murder of six women, who disappeared from Vancouver's drug-infested lower eastside neighbourhood.
All of the women were employed in the sex trade and had battled drug addiction. Pickton, 53, has pleaded not guilty to all of the charges. If convicted, he would face life in prison.
Sixty-one women, including Pickton's alleged victims, vanished from the lower eastside neighbourhood between 1983 and 2002.
Previtt reportedly told the seven men and five women of the jury that Pickton murdered and dismembered the women, disposing them off on the farm.
Human bones and teeth that provided DNA evidence from each of the six victims were found on the property in suburban Port Coquitlam. Justice James Williams had previously warned jurors that the details they would hear were akin to a "horror movie".
Another trial, scheduled after the current proceedings wrap up, will see Pickton charged with 20 other murders. The trial is expected to last for a year.
