Sarah Payne's mother Sara forced to quit Twitter after "years of stalking and harassment' from trolls Writing on Twitter, friend and fellow campaigner Sky Keenan wrote trolls "have caused so much distress @DrSaraPayne has been forced to close down her twitter account." Ms Payne's eight-year-old daughter Sarah was abducted and murdered by Roy Whiting in 2000 near her grandparent's home in West Sussex. Convicted paedophile Whiting is serving a life sentence for Sarah's murder. Many of the abusive tweets, according to Ms Keenan, related to Sarah. She claimed to The Independent that Ms Payne, who Ms Keenan worked with "everyday" for 12 years on campaigning group Phoenix, and a number of her associates had suffered "years of stalking and harassment" across various social media platforms. They are understood to have reported the allegations to police.
