This is the second weekend in a row where there has been reports of a girl stabbing someone for Slender Man. Instead of being 12 year old girls, this time it was a 13 year old girl who attacked her mother.
She was wearing a white mask (probably similar to Masky in Marble Hornets if I am to hazard a guess) and waited in the kitchen for her mother to come home. When her mother walked in, the girl attacked her with a knife.
