TACOMA, Wash. -

Steven Powell wants the state of Washington to pay for court-ordered sex offender treatment he says was denied while serving time in prison for voyeurism.

Powell filed a motion in Pierce County Superior Court that will be heard on Friday.

The News Tribune reports (http://bit.ly/1gB7D5K ) a response to the motion filed by a state lawyer for the Department of Corrections says Powell did not qualify for treatment in prison under the way he was sentenced.

The 64-year-old Powell was released last month after serving a 30-month sentence for taking photographs of two young neighbor girls.

Powell is the father-in-law of Utah mother Susan Cox-Powell, who disappeared in 2009. His son, Josh Powell, was a suspect before he killed himself and his two children in an explosive house fire in 2012.
