A Knoxville man is sentenced to spend 60 years behind bars for producing child pornography.

Knoxville Police were contacted by the Royal Canadian Mounted Police in October 2017 about a video of Matthew Estes and a 16-month-old victim that was posted on the dark web .

In May of that year, officials say KPD also received a video from the Santa Barbara County District Attorney’s Office that also showed Estes and the 16-month-old victim.

That video was found on a device belonging to a suspect who was charged with possessing child pornography.

On Tuesday, Estes, now 26, entered a plea agreement to plead guilty to two counts of production of child pornography and was sentenced to 720 months in jail. Once released, he will be on lifetime supervision and will be required to register with the state sex offender registries and comply with special sex offender conditions.
