Powell's parents have long believed that Steve Powell knows something about her 2009 disappearance. Her father, Chuck Cox, says he hopes a looming prison term would push Steve Powell to speak up.
The trial itself largely ignored Susan Powell, even though the images used as the basis of charges were found in Steve Powell's home during the missing-persons investigation.
Authorities said they found images indicating Steve Powell had an obsession with his daughter-in-law, though they focused the voyeurism case on photos of two young girls who lived next door to him.
Juror Dodd Tremaine says the Susan Powell investigation played no role in their verdict Wednesday.
Susan Powell's husband Josh killed himself and the couple's two young children earlier this year.
