Amazon Pulls Serial Killer's Book After 1 Day Pig farmer proclaimed his innocence in manuscript By Newser Editors and Wire Services Posted Feb 23, 2016 1:32 AM CST 32 comments Comments Robert Pickton was convicted in 2007 of six counts of second-degree murder. (Anonymous) (Newser) – A book reportedly written by Canadian serial killer Robert Pickton was removed from Amazon's website a day after being put on sale online following protests by authorities in British Columbia. Publisher Outskirts Press issued a statement saying it had asked Amazon to remove the book from its website and apologizing to the families of the victims "for any additional heartache this may have caused." Pickton, now 66, was convicted in 2007 of six counts of second-degree murder in the deaths of sex workers. Pickton slaughtered the women at his pig farm and fed some remains to his pigs. He was sentenced to life in prison. Some 20 other murder charges were stayed, though DNA from 33 women was found on the farm and he told an undercover officer he had killed 49. By Monday afternoon, the 144-page memoir titled Pickton: In His Own Words was no longer available. CTV News reports that the handwritten manuscript, which proclaims Pickton's innocence, was apparently passed to one of Pickton's former cellmates in the maximum-security Kent Institution. Authorities in British Columbia promised to introduce a law to prevent offenders from profiting from their crimes. "I am at a loss for words. To think about the pain that he's prepared to willingly cause all of the families of those people who he murdered," British Columbia Premier Christy Clark told reporters. "I have trouble understanding it and I think people will want to know that their government is doing everything it can ... to stop him from profiting from this at the very least."
