The girl behind the attack is currently in a juvenile detention center.
An unnamed Ohio woman reached out to local reporters to share her story of what she believes was another Slender Man-related attack.
The anonymous mom said that her 13-year-old daughter was waiting for her in the kitchen dressed in all black with a white mask, and attacked her in the face and neck with a knife. She did not say when, however.
The 13-year-old reportedly had a history of mental health issues and really loved horror fan fiction, and had written pieces involving Slender Man.
If the attack was related to Slender Man, it would make the 13-year-old the third young girl with an interest in creepypasta and Slender Man to orchestrate a stabbing attack.
