Cities and towns all over the country are always giving money and encouraging these ‘artist’ communities to come into town and setup shop. They give them old warehouse buildings and all kinds of breaks because they think that it brings culture.
In reality its just a bunch of hippy vagrants that need a place to squat for almost no money so they can smoke dope and create junk “art” out of twisted metal and garbage.
My guess is that many of the dead were 'off the grid' and will be impossible to identify.
