ASHLAND, Ky. (WMDJ) — A Paintsville man will spend 25 years in federal prison after being sentenced Friday in a child exploitation case involving a teenage victim.

Henry Jonathan Ritscher, 44, previously pleaded guilty to producing child pornography in federal court. Court records show the charge stemmed from incidents involving a 15-year-old girl who was a guest in his home.

Investigators said the case came to light in September after the teen discovered a video of herself on Ritscher’s phone while waiting in a vehicle during a pizza pickup.

Authorities later determined Ritscher had secretly recorded the girl while she was showering and changing clothes over a period of roughly 18 months.

As part of his sentence, Ritscher was ordered to complete a sex offender treatment program while incarcerated. He will also be required to register as a sex offender for 15 years following his release from prison.

Ritscher was taken into custody following Friday’s sentencing hearing.
