A DNA database question: For solving crimes.

Ok. People know about this stuff better then I do, so here I turn.

I was watching some stories on the upcoming anniversary of the murder of Jon Bennett Ramsey. It's been almost 20 years. The issue I am wondering about is this. Apparently there was DNA of an unknown male that may belong to the killer. Identifying that male would probably help in solving the case or excluding the suspect. Now if he was in a database he would probably be matched right now. I'd imagine the DNA bases that are out there are huge. If not a match could the DNA be matched to a closest match? Or am I way off base here? I'm operating on the assumption that at least everyone has a 5th cousin that's in the database. I am just wondering if you could find a closest match to narrow your search and from there prob family lines to keep narrowing the search, until inevitably you find the source of the DNA.

I have little idea if this is at all possible, so I defer to others much smarter then I.
