Slenderman av Kathleen Hale

The 2014 Slenderman stabbings in the Milwaukee suburb of Waukesha, Wisconsin, shocked the local community and the world. The violence of Morgan Geyser and Anissa Weiser, two twelve-year-old girls who attempted to stab their classmate to death, was extreme, but what seemed even more frightening was that they had done so under the influence of an internet meme, the so-called 'slenderman'. Slenderman tells the full story for the first time, in deeply researched detail.Morgan and Anissa were brought together by their shared love of geeky television shows, and their discovery of the Creepypasta website's scary stories could so easily have come to nothing. But Morgan was suffering with early onset schizophrenia. She believed that she had been seeing Slenderman for many years, and that the only way to stop him killing her family was to bring him a sacrifice.Her victim, Payton 'Bella' Leutner, miraculously survived the attack but was left deeply traumatised, while Morgan and Anissa were immediately remanded into jail, and the severity of their crime meant that they would be tried as adults. Slenderman is both a page-turning true crime classic and a compelling search for justice.
