From the Standard-Examiner in Utah:

Peterson served the full 15 years of a one- to 15-year prison term for child molestation because he refused to admit guilt to the state Board of Pardons.

And:

Peterson’s lawsuit includes sworn affidavits from his two children, who say they were coerced by their mother and stepfather to tell authorities their father sexually molested them. The son and daughter were 11 and 9 at the time.
