Plus all of the potential suspects. It would be nice to know what, if any, backlog there is in processing the dna of RSO's in general and getting the profile attached to them. I'd bet anything there is a backlog.
This case is prob a nightmare in terms of dna. Let's say that they come up with someone in the neighborhood whose dna matches up. They are going to claim that someone put her in the garbage near their garbage and that's how their dna got on her. I can see it coming. LE will have to have other strong circumstantial evidence as well to make a solid case here.
A lot of these garbage dump cases we've seen before have been cases where the husband was the perp and there was other evidence implicating him and they were actually looking for that specific woman's body when they found the remains. Finding the body was kind of coup in the case. Or, the bodies have been found but have not been associated with an identity, and the case has kind of stalled from there - like these murders, did they ever find the killer?

It's better when they are able to find the body in the actual dumpster - those cases seem to have decent solve rates. I think there was a case of a body (of an adult woman) being found in FL in recent months and that suspect has already been arrested (edit - there was, I found the link after I wrote this part:

I'm really hopeful that since they searched each truck's trash after it was dumped that they will be better able to judge the identities of those people who dumped the trash most in proximity to the body. In a weird way, it may have helped if there WAS compaction in that event, because it might have kind of bound garbage from one area together in one spot. But I do agree with MommaD that for all we know LE could have asked them not to compact on that day. In any case, searching one truck at a time would sure cut down on the contamination from all of the garbage in the dump being raked over the remains and anything with the remains over and over again. That would really make all the different dna - and finding specific people's garbage even more crazy.
