A 54-year-old Issaquah man faces up to nine years in prison after pleading guilty Friday to child pornography charges in federal court.

According to details in a plea agreement, Gregory Mark Molley installed hidden cameras in the bathrooms and bedrooms of his home for the purpose of filming children.

Molley is scheduled to be sentenced in U.S. District Court on March 15, 2016.

Molley was arrested after an investigation by the King County Sheriff’s Office and the United States Secret Service as part of Project Safe Childhood, a Department of Justice initiative maintaining resources to investigate and prosecute the sexual exploitation and abuse of children on the Internet.
