Winchel, who has been in custody since February 2015 was also ordered to pay more than $1.4 million in restitution.

He admitted he has downloaded child pornography since approximately 1994. Winchel thought he would be able to trade child pornography with others if he produced his own material. He had access to an 18-month-old child, and took sexually explicit photos of himself with the child. He also admitted using a spy cam to capture minor girls using the bathroom when they were in his home and a nanny cam to capture minor girls in various stages of undress in his home.

Winchell moved to Rockwall from Indiana in 2013, transporting the videos he had recorded of minor girls from Indiana to Texas. He admitted that when children visited for sleepovers at his home in Rockwall, he filmed himself engaging in sexually explicit activity while in proximity of the minor children who were asleep.

Law enforcement executed a search warrant at Winchel’s residence in February 2015 and seized several media items.  An IT specialist, Winchel had used his computer skills to try to mask his computer from law enforcement. The forensic analysis, however, revealed that Winchel’s collection of child pornography, which he had categorized and organized, was approximately two terabytes in size.  Law enforcement further determined that some of the images and a video Winchel had involving an 8-year-old minor victim were produced in late July 2014. Law enforcement found evidence that Winchel produced child pornography and images and videos of five minor victims.

Anyone who knows of someone who may have been victimized in this case is asked to contact the FBI at 972.559.5000.
