Robert William "Willie" Pickton (born October 26, 1949) of Port Coquitlam, British Columbia, Canada is a former pig farmer and serial killer convicted of the second-degree murders of six women. He is also charged in the deaths of an additional twenty women, many of them prostitutes and drug users from Vancouver's Downtown Eastside. In December 2007 he was sentenced to life in prison, with no possibility of parole for 25 years – the longest sentence available under Canadian law for murder.
During the trial's first day of jury evidence, January 22, 2007, the Crown stated he confessed to forty-nine murders to an undercover police officer posing as a cellmate. The Crown reported that Pickton told the officer that he wanted to kill another woman to make it an even 50, and that he was caught because he was "sloppy".
On February 5, 2002, police executed a search warrant for illegal firearms at the property owned by Pickton and his three siblings. He was taken into custody and police then obtained a second court order to search the farm as part of the BC Missing Women Investigation, when personal items (including a prescription asthma inhaler) belonging to one of the missing women were found. The farm was sealed off by members of the joint RCMP–Vancouver Police Department task force. The following day Pickton was charged with storing a firearm contrary to regulations, possession of a firearm while not being holder of a licence and possession of a loaded restricted firearm without a licence. He was later released and was kept under police surveillance.
