Last week we told you about a tragic murder attempt in which two pre-teens stabbed their friends nearly to death in the name of a fiction creature named “Slender Man”.

Just days later it happened again, this time with a teen putting on a white mask and stabbing her mother.

WLWT out of Cincinnati reports that a Hamilton County mother says her daughter’s attacking her with a knife could have been a result of the fictional horror character Slender Man.

Eric Knudsen (“Victor Surge”) of the Something Awful forum created the Slender Man as a meme back in 2009. Explains Wiki, it is depicted as resembling a thin, unnaturally tall man with a blank and usually featureless face, wearing a black suit. Stories of the Slender Man commonly feature him stalking, abducting, or traumatizing people, particularly children

“She had her hood up and had her hands covered with her sleeves and the mask,” the mother said.

She said her 13-year-old daughter was obsessed with the fictional character Slender Man.

“She was someone else during that attack,” the mother said.

Her daughter allegedly attacked her with a knife in the kitchen of their home.

The daughter is in the Hamilton County Juvenile Detention Center.

The mother said her daughter has mental health issues but that she never imagined anything like this would happen.

“I came home one night from work and she was in the kitchen waiting for me and she was wearing a mask, a white mask,” she said.

The mother said her daughter’s writings and drawings have always been dark. They referenced demons, being insane and falling into darkness.

“(She) mentioned playing a role. (I) got the feeling she was playing a role. It didn’t feel like her at all,” the mother said.

The mother said that after hearing about the two 12-year-old Wisconsin girls allegedly stabbing their friend to please Slender Man, she thinks her daughter was under the same influence.

“We found things that she had written and she made reference to Slender Man. She also made references to killing,” the mother said. “She even created a world for Slender Man in the game mine craft.”

Slender Man stories often feature him stalking or traumatizing people.

“We do have to police what they do and what they read,” the mother said.

The girl is facing charges as a juvenile. Her family has not allowed to discuss the case with her but her mother said she told other people that she does not remember the attack.

Her mother was treated for minor injuries in the attack, including cuts on her neck and face and a puncture wound on her back.
