On Thursday in Ulster County Court, 54-year-old Jeffrey C. Brown, 54 of Saugerties pleaded guilty to course of sexual conduct against a child in the, a class B violent felony.

Brown admitted that between September 1, 2014 and December 29, 2014, he had sex at least once and engaged in at least two acts of sexual conduct with a child who was under the age of 13, officials say.

An investigation conducted by the Ulster County Family and Child Advocacy Center led to Brown’s arrest on August 25, 2016.

“This man stole the trust and innocence of a child which cannot be replaced,” Ulster County District Attorney Holley Carnright stated. “It took great courage for this child to come forward and expose this man for what he is, a pedophile.”

Brown is scheduled to be sentenced on April 24.
