“My dad is the most manipulative person I have ever met in my life,” she claims, adding, “He convinces people of things that you would never even imagine. He even manipulated me for a lot of years.”

Monica says she believes John molested her when she was a small child. “I don’t know when the sexual abuse exactly started, but there’s a specific memory when I was four years old that occurred in the bathtub.”

Monica claims she blocked out all memories of the alleged abuse by her father but began having “flashbacks” when she went into therapy as a teenager.

“There’s absolutely no doubt in my mind that it happened,” says the 20-year-old who currently has an order of protection against John. “My order expires in three days. I want to tell my dad that I never want to have a relationship with him and that he needs to leave me and my daughter alone.”

Monica’s mother, Danuta, claims she witnessed John touching her inappropriately when she was a baby, and also claims she found him molesting Monica’s younger brother 13 years later when the boy was six. John vehemently denies ever sexually touching either of his children and says he’s willing to take a polygraph to put the allegations to rest.
