You used the image earlier to describe Iowans as being like ducks on the water.
LE is like that only more so.
In most cases without direct evidence of foul play, LE almost universally seems to play it safe by refusing to say what they think happened. In good part, I think it's because they don't want the possible perpetrator(s) to get a clear view of what is going on with the investigation.
I think that LE is working a whole bunch of different possible lines of inquiry right now. I don't think they're at the point of narrowing down the suspect pool, they're still at the point of throwing more names into it.
They're clearly still conducting searches but not the kind of search that can be delegated to volunteers.
To give one example, since meth use has been connected to one of the families, I'm sure they are looking at all those possible angles. Searching the property of a meth dealer is definitely something you can't delegate to a volunteer, not even just walking by and looking at what might be seen from the sidewalk.
Not having seen this much (I'm brand new to this site, don't watch CSI's or what have you), I'd never considered this, and it makes sense. Especially the part about not letting a perp in on where the investigation is or might be headed.
And I'm not saying they should have had volunteers go door to door searching homes, just that I know for a fact there were 500+ ppl willing to call in to work to help in any way possible. I suppose at some point the law of diminishing returns comes in to play there, though.
I guess I'm just frustrated, having expected to have found some answers to some questions by this point, or to have had some credible tip come in by now. After all, we have all the local and county, and the best state and national crime-solvers descended on our little town, and we've got nothing, just repeated press conferences with "nothing new, we're hoping someone calls in to say they saw the girls." It shakes my confidence, I guess, my Iowan comfort zone - broad as it is - feels very violated.
