Robert Pickton - Canadian serial killer, serial rapist, former pig farmer and possible cannibal. Fed the bodies to pigs, and maybe mixed it with pork that he sold.
The Crown reported that Pickton told the officer that he wanted to kill another woman to make it an even fifty, and that he was caught because he was "sloppy".
He will be up for parole in a few more years. Hopefully they recognize that he is at high risk of killing another woman if they let him out.
