The Man In The Mansion

The murdering mansion is for all to fear especially that person that lives there. Legend has it the wealthy Sangster family had been perfect. Until their youngest boy no older than the age of 12 had gone mentally insane. Taking one of his fathers guns he murdered both of his parents by shooting them in the head with all of his bullets, his 16 year old brother by stabbing him multiple times in the back, he even drowned his 3 year old little sister, and just when it couldn't get anymore sinister he ate them.
One day when the girl across the street is walking back to her abusive brother at home she is shoved in the eerie murder mansion and has to encounter the horrors all night. When she finally is let out she soon finds out that her home is something to fear far more than the legends of the mansion.
