After a struggle of several days, Dorothy Barnett-Griffin has died, presumably from the after-effects of drowning during the 2007 Ironman Florida swim. She was a wife and a mother of three.
How very, very sad.
I didn't see this either until a day or two ago - the autopsy from Barney Rice, the guy who died at IMFL last year, indicated a definite drowning. The didn't release the autopsy results for over 6 months: http://www.newsherald.com/archives/article.display.php?id=71565
No heart problem, as was widely rumored.
I don't know about anyone else, but these deaths definitely make me think hard about whether I want to attempt any 2500-person mass swim starts ever again. I think they're needlessly risky.
