David G. McMillen remains free while awaiting trial. He denied owning or installing the camera.
Yakima Herald-Republic reports the 52-year-old Terrace Heights man was an 18-year employee of the Selah School District, located just north of Yakima in Central Washington.
He was forced to resign in October 2011 after the camera was found in his ninth-grade science class. He was paid nearly $17,000 not to challenge his termination.
