Welcome to the Blast from the Past
The link for the Riggs-Hunt pic is http://www.gstatic.com/hostedimg/ec7...3ec569_landing
I wish I could provide more, but other than the exact link it appears to be a dead end.
Your uncle's tragic early death touched a real chord in many hearts. Have you seen this article by bud Collins in Sports illustrated? This article also mentions Jacque and Pike, who I am happy to see also saw your post.
Please feel welcome to post about your uncle in this space. Several of us would love to know more about him.
