The stars of TLC's new show Sister Wives
are under police investigation in Utah for a possible charge of felony bigamy.
Police in Lehi, Utah, said Monday they began looking into salesman Kody Brown and his four wives before the show premiered
"At the conclusion of the investigation, the evidence will be forwarded to the Utah County Attorney's Office for review and possible prosecution," says Lt. Darren Paul.
Police acknowledged that publicity over the show's announcement prompted the case. Bigamy is a third-degree felony in Utah but is rarely investigated.
Brown and his wives Meri, Janelle, Christine and Robyn have 13 children and three stepchildren. They say they will lead a lifestyle that they want, even if it means breaking away from tradition
"If we raise productive, contributing members of society who are moral and ethical, that's our final goal, whatever their path is," says Janelle, 40, who has six children with Kody.
