Troubled ChildhoodEdit

Billy Child

Billy as a child

Billy was born in 1970 to Constance and Franklin "Frank" Lenz under the name William Edward Lenz. Born with a rare liver disease that made his skin yellow, he was despised by his mother who psychologically and physically abused him. Billy's father, however, was very kind and doted on his son, and tried to bring happiness to him whenever his wife tried ruining events like Christmas. It could be said that Billy's father was quite possibly the only positive influence in his life, this positive influence sadly was not to last. Mrs. Lenz was unsatisfied with her husband and at an unknown period of time took a new lover, whether or not Billy knew about the affair is unknown. Then on Christmas in 1975, when Billy was five years old, Mrs. Lenz and her lover murdered her husband with a claw hammer right before Billy's eyes, this event had a profound effect on him which left deep psychological scars for years to come. Noticing Billy hiding under the bed, Mrs. Lenz realized that he had seen the murder and she locked Billy in the house's upstairs attic. Billy would remain imprisoned there for 16 years. In 1982, Mrs. Lenz was frustrated that she was unable to conceive a child with her lover because he was impotent. After realizing this, she went up to the attic and raped Billy as a last resort since Billy was the only other man in her life. Even though Billy was 12 years old at the time, Mrs. Lenz becomes pregnant with Billy's child and that same year she gave birth to a girl who she named Agnes, who, despite being inbred, was treated like a little queen by Billy's mother and her lover, the love that Billy was denied by his mother.


However on Christmas of 1991, the psychological scars from the years of abuse that he had endured from his mother, his rape, and quite possibly the kindness they treated his sister/daughter Agnes while they treated him with cruelty, that finally made him snap. Escaping from the confines of the attic, he attacked Agnes covering her head with plastic he then proceeded to disfigure her face with a knife so he that could make her as ugly as what Mrs. Lenz thought of him. After he did this, he then proceeded to remove one of her eyes and ate it before his horrified mother, taunting her by saying that that she was “his family now.” His step-father tried to save his "daughter" and then tried to beat Billy to death, but Billy was more fast, he then murdered his mother’s lover by stabbing him through the eye with an umbrella. Billy then grabbed his mother, the source of all his suffering over the years and wrapped Christmas lights around her neck before beating her to death with a rolling pin. After this, he then proceeded to use a cookie cutter to make “cookies” out of her flesh. When the
