Years back there were cattle, then horse, multilations that went unsolved. This had been going on for decades. A few had some patterns on locations.

While yes, there are heat domes, nefarious reasons while food processing plants targeted. Pull back and look at locations. Is there a pattern. Talked to a relative today north and said cattle trailers have been running stock north at early hours non stop. Why north into Nebraska and South Dakota?

I do believe 10k are dead in Kansas from article I read earlier. Something more than heat.
