I can't see him leaving the country. A 70 year old guy, probably born in Tennessee. I don't think he would be happy in some foreign country. Besides, he gets indicted for first degree murder, most countries would ship him back, to face the music. I believe Ireland does not have an extradition treaty but most countries do.
Fascinating thread, this is one of the reasons I am on this forum, a hunting disaster news story that would not make the news around here.
