A woman interviewed on CNN news today revealed that her neighbors were found dead in their home in New Orleans and rescuers had apparently marked the building as having been searched, with no bodies found. She entered the home after having "suspicions" that something (likely foul smells) was amiss in the "abandoned" home. She and another neighbor entered the home and found the severely decayed corpses of the two elderly residents inside.
The Army/Guard only had so much authority during the searches. Kicking in a door when nobody is shouting "Help!" is called "breaking and entering". So, many of the houses were only searched by looking in the windows for bodies. Some of the more desparate areas were searched more thoroughly, of course, but many of the areas couldn't be accessed because the water was too high; these were given exterior searches as well. These houses were marked with "ext" on the front to show that the interior had not been searched. Later, when the water went down, many of these areas were searched again.
It was already understood that more bodies would be found when we let the residents back into the curfew districts and they went to check on their elderly relatives.
I guess the rescue/searchers were just a little too busy that day, huh?
We're talking about a city the size of... Surprise! A CITY! with only a few thousand troops to search it. It's difficult to imagine the circumstances and the scope of the project, but try imagining an area the size of, well, roughly a "city", and imagine that it was washed off the map and you and your buddies were looking for something the size of, say, a "person" on the bottom of all the rubble.
The smell isn't a clue, because the whole city smelled like someone had taken a **** on a dead cat before dousing it in rotten eggs, so no real help there until you get
right on top of it. The windows are covered inside and outside with a layer of septic scum from the receding waters, so you can't just peek into the livingroom while strolling by. Everything inside, from the walls to the beds to the couches, is covered in a layer of filth, mold, and mildew, so the color contrasts are no help; a white corpse and a black corpse both look just like the couch. The mold inside combined with the film on the glass makes visibility low to begin with.
Having smelled decayed, half-submerged bodies before, I can't understand how they're still not discovered. Who nose?
The whole city smells. Remember, all those places where your body waste goes were flooded out. Think of it like like trying to sniff out one particular turd in a whole row of port-a-johns.
