Thanks for linking to the WTVA article. Google’s spider must be crawling slow today. They had not picked up this article yet.
One difference I see from your article and what I heard in an interview this morning with the New Albany asst police chief. The chief said that the coach was treated and released. The WTVA article says that he was admitted for surgery.
Whoever did this would be much safer if they turn themselves in to police. Country justice will be a lot swifter and stronger if the “good ol boys” catch them.
