Slender Man
On May 31, 2014, two 12-year-old girls from Wisconsin lured their friend to a wooded area and stabbed her 19 times. They did it all to impress Slender Man, a faceless bogeyman whose mythology has proliferated on the Internet. The victim survived and is recovering, and the pair are being tried as adults. A second Slender Man-inspired attack occurred on June 5, when a 13-year-old girl from Ohio swung a knife at her mother while wearing a white mask.
