The Tennesse law governing this would be Section 39-15-401.  Depending on the age of the child it can be treated as a Felony (Class D) - this includes a possible sentence of 2 to 12 years, with a maximum fine of $5,000; or this can be treated as a Felony (Class E) - this includes a possible sentence of 1 to 6 years, with a maximum fine of $3,000; or this can be treated as a Misdemeanor (Class A) - this includes a possible sentence of 11 months and 29 days, with a maximum fine of $2,500.Here's a link to the statute: http://www.state.tn.us/tccy/tnchild/39/39-15-401.htmAs for the assault you didn't specify what kind of assault it was - aggravated, domestic, child, aggravated on a child, etc.  Without more specifics I can't say what the penalty will be other than if it was the sexual assault of a child or the aggravated sexual assault of a child, than it is treated as a felony and anyone convicted is subject to prison time. I think you'll agree that anyone guilty of this kind of demented behavior deserves everything that they get.
