I am probably well off the the track here, but this reminds me of the Zebra Killings for some reason. Athletic, academically gifted, well-liked young people - the flower of their generation, in symbolic terms at least - appear to be getting picked off in a not-quite nationwide murder campaign.
A noticeable factor, to me anyway, is that every single victim is white as well as male (though in the areas the victims came from I suppose that is not altogether statistically unlikely).
But, for no reason other than intuition and the Sinsinawa graffiti that was found at one of the sites (and the later finding of a body at Sinsinawa avenue) I'm thinking not of a Black Supremacist group (or, for once, of agents of the US Secret State) but a more organised Native American equivalent of the Zebra Death Angels.
Pure speculation here, I stress. A hunch. God knows, historically, the Native Americans have motive - though there is of course no excuse for the murder of these young men, and zero real evidence that Native Americans are involved (stressing that again).
Sinsinawa has history, though. During the Black Hawk war (which Lincoln fought, or marched, in) it was the scene of a small but pivotal raid by the Indians that nearly made the entire population of Plattesville up and leave out of terror. Only two white men killed - but a whole community so scared that the whites were ready to up and leave for good. If I were the leader of a serial-killing supremacist group, this would be the kind of incident I would take as an inspiration and a model.

Sinsinawa mound is now home to a large University, as well as a convent for a group of very noisily anti-War Dominican Nuns.
The main (though certainly not the only) problem with my hunch is that if this was being done by small interconnected groups from the Native American reservations in order to terrify the local white communities, they wouldn't be so careful in covering it up, and they'd be a lot more vocal in claiming responsibility and stating their aims.
Unless the killings fulfill some other function. Ritualistic. Or "slowing the herd" by taking out it's apparent front runners.
The fact that the murders seem to go back as far as '97 without anyone saying "That was us, and this is why" also goes against my idea.
These are just thoughts that came to my mind, and I don't mean to offend anybody, or suggest that it can't be another group responsible (it most likely is). Just thought I'd mention it.
Those smiley faces creep me out. Didn't they used to be printed on Ecstasy tablets sometimes back in the day? They also look like forum emoticons, but I don't want to even consider that!
