Ok, good. Knowing his name is an important first step. Start googling him. Use “rape” and “convicted” in quotation marks in your search to try and pull up newspaper articles about the crimes, which may have been committed in another city or state, and to cut down on the number of hits you get of same-named, but unrelated people.
Good luck!
Yes it is good and bad unfortunately the guys last name is Smith and his first name is just as common so finding anything is going to be difficult.
