More tragedies connected to 'Slenderman'

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

She also had a knife — and began attacking her mother — right there in the kitchen.

“We found things she had written and she made reference to Slenderman. She also made references to killing. She had even created a world for Slenderman in MineCraft — in the game MineCraft,” the Ohio girl’s mother said.

Police say 14-year-old Lily Marie Hartwell of Port Richey, Florida set her home on fire as her mother and brother slept inside. According to the New York Daily News, police say Hartwell soaked a towel and bed sheet with bleach and rum — before setting them on fire inside the home.

After allegedly setting her home on fire, the New York Daily News says the girl walked to a nearby park and went to sleep in a bathroom.

The New York Daily News says the girl’s mother and brother were able to get out of the home. The mother, realizing her daughter wasn’t outside with them, apparently tried running back into the home, but the New York Daily News says the heat was too much. It took firefighters several hours to knock down the flames.

Hartwell has been arrested and charged with one count of arson, and two counts of attempted murder.

The New York Daily News says the girl was a frequent visitor of websites detailing gruesome acts committed by Slenderman — and makes reference to the case involving the 12-year-old girls out of Waukesha, accused of stabbing their 12-year-old friend 19 times — leaving her to die in the woods.
