"Sister Wives" Family Won't Face Charges in Utah Kyle Christy/TLC The polygamous family at the center of the TLC series "Sister Wives" will not face criminal charges in Utah. Utah County authorities launched a bigamy investigation into Kody Brown and his four wives in 2010, after which the family moved from Utah to Las Vegas. According to The Salt Lake Tribune, a Utah County prosecutor says charges against the family will not be filed due to a new policy under which bigamy cases will not be pursued against any consenting adult polygamist unless violence, abuse or fraud is involved. Brown and his wives last year filed a lawsuit against Utah County challenging the state's polygamy law. The county seeks to have the lawsuit dismissed in light of its decision to not prosecute the family.
