A 25-year-old man with a history of sex crimes is going to prison for 10 years for the sexual assault of an underage girl.  A Dodge County Circuit Court judge sentenced Nicholas Bradley Tuesday.  He will be on probation for six years when he gets out.  Bradley was convicted in February on a charge of second-degree sexual assault of a child.  The victim was 14 years old.  She told officers she met Bradley on Facebook and had sex with him twice.  She says she told him her real age.  Bradley had been found guilty of sexual gratification with an animal three years ago.
