Thanks for the link to another story of the many who underestimate the various dangers in the Grand Canyon. I have a somewhat morbid facination with these tales. Someone earlier referenced the popular book, I think.

For those interested in this sort of thing, the park's news web page will keep you abreast of the most recent screw-ups and bad-luck tales (the "icyyyyyyyyeeeeeeeeeee" news article from February 16 made the rounds in e-mails most recently). The specific news link title usually contains a word like recover, rescue, helicopter, or body for similar stories, if your browsing.

This is not atypical for any area where you have extremes of topography or weather, combined with extensive use, risk taking, and lack of planning or experience. Some of the other parks post these articles on-line, also.
