Prosecutors seeking 10-year term for Steven Powell
Powell, 62, was convicted last month of 14 counts of voyeurism. The standard sentence would be about four years in prison.
The News Tribune reports prosecutors filed a notice saying he deserves 10 years to hold him accountable for crimes against both girls.
He will be sentenced June 15 in Tacoma.
Powell is the father-in-law of Susan Powell, who disappeared from her home in West Valley City, Utah, in late 2009. His son -- her husband -- Josh Powell killed himself and two sons in a February fire at a home in Graham.
