A former Walker County teacher has entered a "not guilty" plea to federal charges of his having produced child pornography in the late 1990s.

According to reporter Lauren Scharf of WAFF-TV 48 News in Huntsville, Ala., Charles Mark McCormack was arraigned Friday, Oct. 13, and pleaded not guilty. He is currently on an ankle monitor living with his parents in Tuscumbia, Ala., according to the news report.

McCormack, 54, was living in Muscle Shoals, Ala., when arrested on Sept. 27, on a federal criminal complaint charging him with producing child pornography.

According to U.S. Attorney's Office in Northern District in Alabama, sometime between Aug. 1, 1997, and Oct. 15, 1998, McCormack is alleged to have surreptitiously videotaped a 5- or 6-year old urinating in a bathroom in his residence. The videos were intended for distribution as pornography involving a minor.

Records show that in May 2016, federal authorities investigated accusations that McCormack had previously molested a child.

Walker County Sheriff Steve Wilson said his department assisted with that investigation of McCormack, who was then a Chattanooga Valley Elementary kindergarten teacher.

McCormack had been investigated twice for crimes involving children before May 2016, but there was never enough evidence to prosecute the teacher, Wilson said at the time.
