A man from Hamilton has pleaded guilty to distributing almost 50,000 files of child porn on the internet.
Callen Kapschock, 56, was arrested as part of the state's child protection initiative called "Operation Safety Net."
Kapschock is required to register as a sex offender under Megan's Law.
He faces up to six years in prison when he's sentenced in January.
Kapschock is among 79 child predators and child pornography offenders arrested in the initiative.
