I'm going to go out a limb here based on an alleged picture of the perp.
According to reports this is Esteban Santiago who lived spitting distance from the only Mosque in Alaska, making the ISIS sign, and wearing a suspicious rag around his neck.
But, don't worry peeps - he'll be called a "mentally disturbed lone wolf" who had nothing to do with Islam.
Make of it what you will.
Let the spin begin.
