McDougal contacted a teenager through the website in January and forged a relationship with the alleged victim. The two communicated through Facebook and email, the complaint states.
After several months of communication, McDougal asked the victim to send nude photos to him. The victim, believing McDougal was a 17-year-old, took sexual photos with a cell phone and sent them to McDougal, the complaint states.
Meanwhile, a local church leader contacted the Department of Children and Family Services in May to report that an anonymous person had observed child pornography on McDougal's home computer. One of the videos showed a minor walking around a bedroom in a towel, the complaint states.
The Taylorsville Police Department began investigating the case and McDougal admitted during a June interview that he purchased a "nanny cam" that he hid in places where juveniles changed clothing or were naked, the complaint states.
McDougal transferred videos from the nanny cam to his computer, he said. Computer analysts at the FBI's Regional Computer Forensics Lab discovered "several videos and images of a minor in various stages of undress which appeared to have been taken by the nanny cam," the complaint states.
Investigators also discovered sexually explicit images of a 16-year-old girl on McDougal's computer. Several photos focused on the girl's genitalia, the complaint states.
Also during the course of the investigation, a computer seized from McDougal's private office at the funeral home provided evidence that McDougal had been operating a fake Facebook account and storing "several hundred" nude photos of minors on his cell phone and thumb drives, the complaint states.
The complaint states that three alleged victims were interviewed prior to McDougal's arrest, but investigators are continuing to examine whether other victims fell prey to McDougal's advances.
At a detention hearing before U.S. Magistrate Samuel Alba on Wednesday, McDougal was ordered to remain in custody as the court case against him proceeds. Prosecutors told Alba that McDougal is a danger to the community.
McDougal's arraignment is set for Dec. 2. He is being held in the Davis County jail in the custody of U.S. Marshals.
If convicted on federal charges, he faces a 15-year mandatory minimum prison sentence for the production of pornography charge alone, and addition time for the enticement charge.
