During James's trial, he was asked what the first word was that came to his head when he thought about his relationship with his sister Katie, to which he responded: 'Curiosity'.
Katie had the opportunity to respond to her brother, who faced her from just a few feet away, shackled and awaiting transport to his decades-long prison sentence.
"It was sexual abuse, it was not curiosity," Katie said.
"Do you really think so little of what you did to me?"
Katie continued: "You try to blame your substance and alcohol abuse on dad, but in reality, James, it was your mind dealing and processing with your guilt."
James, 31, is appealing his prison sentence with the defense that he was under the influence of drugs during the time he confessed the abuse to police.
At the age of 17, James was primarily entrusted with his sister's care because their mother worked long hours, and their father traveled frequently for his job.
Katie decided to finally speak out about the abuse more than a decade later after her family reportedly disowned James for his drug abuse in 2013. The stress of remaining silent about the abuse brought on seizures and emotional issues for Katie, News Channel 9 reported.
"You stand here today, and throughout this entire prosecution with the mindset that you don't deserve this," Katie said.
As she spoke, her brother stood with his body facing the judge, but his head turned and watched unemotionally as his tearful sister speak about the impact his abuse had on her life.
Katie began laughing incredulously through her tears when she discussed her brother's statement on the stand that 'curiosity' motivated his abuse.
"After hearing that word 'curiosity' the trauma for me continued," she said.
"Just when I thought the memories and the way I felt was enough to make me cold and numb inside, you managed to damage and hurt me again."
She then began sobbing, and reflected on the gravity of the prison sentence handed down to her brother - 32 years. A judge has banned him from contacting Katie for the next four decades.
He previously turned down a plea deal that would have granted him 13 to 15 years in jail, and would have spared his sister from testifying at his trial.
"How does possibility of 32 years sound to you?' she asked. "That's 11,680 days and 280,000 hours. I'm positive that number will matter to you."
'However long I live, I will have a life sentence,' she continued.
"I have the rest of my life to bear the weight of this abuse, and that is that. I will never forget what you have done to me. I will never forget how it felt through those dark days."
Despite the unbelievable trauma Katie experienced as a child, she now plans to dedicate her life to advocating for other children who are victims of sexual abuse.
She is now pursuing a second degree in Criminology from the State University of New York, according to her social media page.
Finishing her speech, she told her brother: 'To be honest, I'm not sure how to end this. I've been waiting for this day for years.
"I suppose a goodbye is an order, but I'd like to say one last thing. I don't hate you. I hate what you did.
"But I hope you and your self centered, egotistical a** remembers my last words to you and you'll be reminded every single day that you're in prison for your curiosity."
