A mother in Hamilton County, Ohio, says her 13-year-old daughter slashed her with a knife after possibly becoming obsessed the fictional stories of “Slender Man.” It would be the second attack inspired by the creepy character.

The mom, who has not been identified, reportedly come home from work to find her teen daughter wearing a “white mask” and holding a knife. The woman was reportedly stabbed in the back and suffered cuts on her face and neck during the attack.

The woman believes her daughter, who reportedly suffers from mental health issues, was influenced by Slender Man stories.

“[She] mentioned playing a role. [I] got the feeling she was playing a role. It didn’t feel like her at all,” she told WLWT-TV.

The 13-year-old had apparently written notes about Slender Man and made references to “killing.” The girl also reportedly “created a world for Slender Man in the game Minecraft,” according to the mom.

The 13-year-old is set to face charges as a minor.

In Wisconsin, two 12-year-old girls were recently charged with stabbing and nearly killing a friend after they told investigators that they planned the slaying to curry favor with a fictional character whom they read about on a horror fiction website — Slender Man.

Slenderman is a paranormal being who lurks near forests and absorbs, kills or carries off his victims. In some accounts, he targets children. He looks like a long-limbed, lean man in a black suit, but he has no face. In some accounts, he has tentacles protruding from his back.

Eric Knudsen of Florida created the character in response to a call for submissions from the online forum SomethingAwful, said Shira Chess, an assistant professor at the University of Georgia who has researched Slenderman’s origins. Knudsen posted the first photos along with a fictional news story under the username Victor Surge on June 10, 2009. He did not respond Tuesday to an email seeking comment.

Other writers, artists and programers later created additional stories, movies and video games featuring Slenderman. Websites show what appear to be photographs of the character, lending it an air of authenticity.

“It feels real,” Chess said. “A 12-year-old potentially isn’t going to know the whole origin of the story.”
