Miller, now 54, dressed in feminine clothing and went by the name Amy George while committing the crimes in Scotland last year, and his gender identity was repeatedly brought up during the ensuing trial.
According to the Scottish Sun, sources within His Majesty's Prison Edinburgh claimed that Miller "dresses like a man [and] looks like a man," adding, "there's nothing feminine about him." The convicted pedophile also reportedly uses male pronouns when addressed by prison staff.
The incident took place in February 2023 in the Scottish Borders. Miller offered his victim a ride home, but instead took her to his house and locked her in his bedroom, where he proceeded to repeatedly sexually abuse the child, forcing her to watch pornography and "fetish videos," and telling the victim he was her "new family."
He pleaded guilty in May to abduction, sexual assault, watching pornography in the presence of a child under the age of 13, and possessing 242 indecent images of children. He was subsequently sentenced to 20 years in prison and eight years probation.
During his hearing, Miller's decision to present as a woman while carrying out the evil deeds was deemed a "significantly aggravating feature."
"Would an 11-year-old girl have willingly entered your car had you presented as a man?" Judge Lord Arthurson asked, per the Independent. "The answer is that obviously, she would not. Your intentions were wicked and predatory, and clearly involved a substantial component of planning."
Miller's defense attorney, Victoria Dow, argued during a sentencing appeal earlier this year that "too much weight has been attached to that factor," adding that, "it is clear the appellant has experienced psychological difficulties throughout his life.""Prior to the offense," she added, "he was struggling to cope with a number of factors in his life. He was soothed by the feeling of control."
