An Issaquah man who admitted to filming teen girls in the bathroom and bedrooms of his home was sentenced to eight years in prison Tuesday.

U.S. District Court Judge John Coughenour sentenced Gregory Mark Molley, 54, to eight years in prison and 15 years of supervised release on Tuesday.

Molley pleaded guilty in December to receipt of images of minors engaged in sexually explicit conduct.

Molley’s case was investigated by U.S. Secret Service and King County Sheriff’s officials under Project Safe Childhood, a Justice Department initiative.

According to charging documents, investigators found an extensive collection of videos of teenage girls changing in Molley’s Issaquah home. The charges brought against him involved five girls, one of whom was filmed in Oregon. Molley was arrested in Multnomah County, Oregon, by county sheriff’s deputies in July before being transferred into federal custody.
