Police in Lehi, Utah told People on Monday that as a result of the show's heavy promotional campaign, the polygamist family is now under investigation. Bigamy is a third-degree felony in Utah, but is rarely investigated.
When the Browns met the media in August at the Television Critics Association's summer session, they said they knew doing a reality show would open themselves and their lifestyle to critique. "I just didn't want to raise my children with the same fear that I was raised with. I'd rather be open and just open to our society," Christine Brown told TVGuide.com. "We're willing to take the risks, which is why we're here."
Brown and wives Meri, Janelle, Christine and Robyn have 13 children and three stepchildren together.
In a statement, the Browns said they were "disappointed" in the announcement of the investigation, but knew there would be risks in doing the series.
LT. Darren Paul told the site, "At the conclusion of the investigation, the evidence will be forwarded to the Utah County Attorney's Office for review and possible prosecution."
It remains to be seen whether the investigation, and any possible charges that stem from it, will affect the series' future. As seen on other TLC shows like Jon & Kate Plus 8, the network is not one to shy away from a little controversy.
Sister Wives drew 2.3 million viewers on Sunday, making it TLC's most-watched series premiere in a year.
The series airs Sundays at 10/9c.
