Missouri does not have have a good handle on where CWD currently exists in the state. Then, when found, do they really have confidence in how it got to where they found it. At least initially, they have a confidence it came from Heartland, right or wrong, they have a starting point. We now have instances of it 100s miles away, with no confirmed path of destruction between. Nothing to go on, so any assumption/theory is based on insufficient supporting logic.
