I'm replying sympathetically to everyone who gets "discouraged" while waiting for developments. This morning I thought of something that might take time, and apologize if it's been mentioned already: wouldn't the hatchet in possession of the "POI" in Colorado be tested for DNA? He's been observed waving the weapon recently in Colorado, and for using one in Indiana in a threatening manner. (Though I do not have previous links to insert here)
Since LE traveled to Colorado, they had reason to officially investigate; perhaps the people they don't think it is, are "people" linked to POI, and not POI himself.
