Miller, 35, was arrested on Jan. 12 after the girl's father, with whom Miller was staying, said he walked in on Miller raping the girl, who was 9 years old at the time. Miller admitted to police that he had been molesting the girl for years, the prosecution statement said.
The father told investigators that he and Miller had been friends for more than a decade and that Miller was staying overnight at their home. The father heard a noise and went to check on it. When he saw that Miller wasn't in the living room where he'd been sleeping, the father rushed to his daughter's room and found Miller raping her. The father held Miller at gunpoint until police arrived.
A forensic analysis of Miller's electronic devices revealed that he had produced at least five videos and 132 images of child pornography involving the victim dating back two years, to when she was 7.
