"Katrina Death Toll May Never Be Known"

As has been discussed here a few times already:

Nearly six months after Hurricane Katrina, more than 1,300 bodies have been found, but the real death toll is clearly higher. How much higher, no one can say with any certainty.

New Orleans Coroner Frank Minyard said a final sweep of homes in the devastated Ninth Ward will be done this month with help from federal officials. After that, he said, any more bodies found will probably be discovered in out-of-the-way places by hunters or fishermen.
