Thanks for the info Don. From the articles it was a Fairchild M-62. "A fisherman reported seeing the crash and said the plane struck some power lines and nosedived into a sandbar in the river."
My boss's brother is an EMT who responded to the call and said they were burred deep in the sand. The helicopter he rode in on kept the rotors turning for fear of sinking into the sand itself.
I don't think I visited that plane during the show. Some pics I took are
here. It might be the yellow one doing a low fly-by?
