An Ohio teen attacked her mother with a knife in the second stabbing linked to the fictional horror character “Slenderman.”

A Hamilton County mother, who asked to not be identified, told a local NBC affiliate that her 13-year-old daughter became obsessed with the Internet meme before she stabbed her.

 “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,” the mother told the station. “She was someone else during the attack.”

The mother suffered multiple minor injuries, including a puncture wound on her back. The girl is facing charges as a juvenile.

The attack comes after two, 12-year-old Wisconsin girls brutally stabbed their friend 19 times as a sacrifice to the mythical character. The mother said after hearing of the Wisconsin attack that she began to suspect her daughter was under the same influence, the NBC affiliate reported.

“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 Slenderman in the game Minecraft.”

A spokeswoman for Slenderman creator Eric Knudsen and an administrator for creepypasta.wikia.com, where the meme was published, have apologized since the first attack and said Slenderman does not teach children to be violent.

“I am deeply saddened by the tragedy in Wisconsin, and my heart goes out to the families of those affected by this terrible act,” Mr. Knudsen said in a statement, the Associated Press reported.
