“…she can’t remember how many times the two had sexual intercourse however can remember the places,” the affidavit reads. The girl went on to list the locations which included her home, Griffin’s home and the Kim Soo Karate studio.

Griffin was booked into jail on two counts of sexually assaulting a child. If found guilty, he faces between 2-20 years in prison and a $10,000 fine for each of charges. provides commenting to allow for constructive discussion on the stories we cover.
