But bodies that have been in the water won't fingerprint very well.
Some will and some won't. However, there are two good things about fingerprints in addition to the obvious. One is that there are millions of fingerprints already on file for a wide variety of reasons, and those records can be searched electronically. That means you can ID people without having relatives to contact. The other good thing is that fingerprint technology has advanced greatly in the last 20 years or so, and now you don't need most or all of a print to make an identification.
So DNA is the obvious choice. With the drawback being that there has to be someone to match it with.
Well, the first thing the authorities will do is some basic detective work. Where was the body found? The address alone may give us a darn good idea of who the person is. As someone noted above, many bodies will not have ID on them, but many will. Many more will be found in homes where other documents will give clues, or in vehicles which can be traced. If bodies were found together, once you ID one you will gain important clues for others. There will be missing person reports saying the person was a male of a certain age and race, last seen wearing the following clothing. When you find someone generally matching a description like that, you will have important clues and a much easier task. Without going on ad nauseum, there will be a lot of good old fashion detective work before they start with the forensic evidence.
In addition, DNA identification is not as complicated and difficult as it sounds. It does take time, and you do have to have relatives DNA to match. Collecting DNA samples is quick, easy and painless -- it's nothing more than some basic paperwork to identify who the sample came from, and then a few seconds of chewing on a cotton cloth to provide a saliva sample. The more difficult thing will be finding the
right relatives to compare, but I'm sure they will not make themselves hard to find. I'm sure that process will start pretty quickly once they get people settled in living arrangements where they will be for a few months, if it hasn't already. I'd think it would eventually become a standard part of the registration routine when a victim is placed in a housing arrangement.
As I said above, there will be unidentified bodies, and there will also be missing people who are never located. I'm not sure what the numbers are, but I know there are still a considerable number of unidentified remains from the World Trade Center and numerous people still missing.
