The father-in-law of Susan Powell, a missing Utah woman, has been arrested after police found child pornography, as well as videos of his daughter-in-law and other females, in his home.

Steven Powell, 61, is being charged with 14 felony counts of voyeurism and one count of possession of child pornography, according to Washington prosecutor Mark Lindquist, the Associated Press reported.

Police found thousands of images of females being videotaped without their knowledge, including Susan Powell in his Washington home, Lindquist said, the AP reported.

Lindquist said the captured images focus on the buttocks and breasts of the women filmed, and that there were many images of underage females.

Two little girls who were filmed used to live in the area, according to authorities, the AP reported.

Susan Powell's sons, who had been staying with her father-in-law, are now in foster care, according to a lawyer for the state attorney general, and her father has asked for custody of them, the AP reported.

We're very concerned for the welfare of our grandchildren, Powell's father, Chuck Cox said, the AP reported. We're doing everything we can.
