ASHLAND, Ky. (WMDJ) — A Johnson County man arrested last year after secretly recording a teenage girl has pleaded guilty in federal court.

Henry Jonathan Ritscher, 43, of Paintsville, entered a guilty plea Monday in Ashland to a charge of producing child pornography.

Investigators say the case began in September after a 15-year-old girl discovered a video of herself showering and changing that had been recorded earlier the same day. Police say the girl was a frequent guest at Ritscher’s home.

The girl told investigators she found the video while waiting inside Ritscher’s vehicle and used his phone while he went inside a restaurant.

A search of Ritscher’s property led to the discovery of multiple surveillance cameras hidden inside a tote in his garage. Police say the camera used to record the girl was concealed inside a phone charging block. Investigators say Ritscher removed the cameras after anticipating contact from law enforcement.

According to police, Ritscher admitted to secretly recording the girl for approximately a year and a half.

As part of the plea agreement, a charge of possessing child pornography will be dismissed. Ritscher faces a sentence ranging from 15 to 30 years in federal prison when he is sentenced May 4.
