A Casper man could spend the rest of his life in prison if convicted of sexually abusing and photographing a young girl over the course of several months.

Stefan Wayne Voltaire made his initial appearance in Natrona County Circuit Court on Thursday, where he was charged with six counts of first-degree sexual abuse of a minor, four counts of second-degree sexual abuse of a minor and one count of sexual exploitation of children.

Voltaire could be sentenced to a maximum of 390 years imprisonment if convicted of all counts.

Charging documents say a detective was dispatched shortly before 3 a.m. Thursday after Voltaire's girlfriend found inappropriate pictures of the victim on a computer belonging to Voltaire.

The affidavit lists groups of photos taken from early June through late February. Several pictures allegedly depicted sexual intrusion, while others allegedly depicted sexual contact.

The victim's mother reportedly told a detective that she saw photos in which Voltaire had his hands on the victim.

Voltaire allegedly told investigators that he had joined an "online erotic community" and participated in a "game" created by other members. The "game" was to find incest pornography videos and create "erotica" videos for others to view, according to the affidavit.

"This idea encouraged [Voltaire] to photograph [the victim] due to his liking of father vs daughter pornography," the affidavit reads. Voltaire allegedly began to photograph the victim's naked body, and would use his cell phone to record himself "punishing" the victim "because of bad hygiene."

"[Voltaire]'s idea of punishment was making [the victim] pull her pants and panties down and hitting [the victim] across the buttocks five or ten times," the affidavit reads. Voltaire also allegedly admitted that he had instructed the victim to pose nude for him, using his cell phone to record video "on all occasions," according to court documents.

Voltaire is being held on $100,000 cash only bond pending a preliminary hearing, which will likely be held within 10 days of Thursday's hearing.
