Susan Powell's father-in-law guilty in child porn case

TACOMA, Wash. -- The father-in-law of Susan Powell, a Utah woman who went missing six years ago, has been found guilty of possessing child pornography.

Steven Powell was on trial since last week for possessing explicit images of two neighbor girls. Jurors returned a unanimous verdict against the 65-year-old man on Monday afternoon.

Powell was ordered held without bail until his August 21 sentencing, The News Tribune reported. He faces up to five years in prison.

Powell was convicted in 2012 on 14 counts of voyeurism for shooting video and still pictures of the girls -- ages 8 and 10 -- from a window as they used a family bathroom. A judge threw out the child porn charges before the voyeurism trial, but they were reinstated by an appeals court.

Powell is the father of Josh Powell, who killed his two sons and himself in February 2012 while under investigation for his wife's 2009 disappearance that gained national attention. Susan Powell was never found.
