There are several ways the government can find out (for example, cross-checking information filings such as tax returns), but typically for state prosecution purposes, it would be someone close to the situation reporting it to authorities. I had a friend prosecuted for it many years ago, and that is how it came to light.
Your friend would be well-advised to get divorced and clear things up, or try and verify that he obtained a divorce. She can talk with an attorney of her choosing (my firm handles these types of matters) or go to the U of U clinic to get free help. See -- http://www.law.utah.edu/probono/free-legal-clinics/

I have had several clients prosecuted for this. The point -- you can NEVER assume that someone won't report it. An upset "second" spouse for example, or the "other" spouse who now wants money.

Agree with Mr. Cave. Never assume someone won't find out. That is like saying you can drive drunk as long as you drive real fast so nobody catches you. Very dangerous. I have had many clients charged under these circumstances.
