I know more than I can say. I am not at liberty to tell how or why? Sorry!
And yes, I know how lame that sounds!!!
I will pull my punches and take my chances.
As far as I can tell every piece of paper and electronic evidence that is in the public sphere and that is acceptable to the TOS of this site has already been linked to.
I cannot find any mention of the $250,000 owed to the brothers by JN until October 23. It then appears in the Probable Cause Affidavit stating that "Jack Diemel said his sons were coming to Missouri to retrieve a $250,000 check from Joey Nelson for cattle."
Multiple news reports on October 23 & 24 contained the following:
KANSAS CITY, Mo. (AP) — The Latest on charges filed against a Missouri farmer in the killing of two brothers from Wisconsin (all times local):
1:15 p.m.
An employee of two slain Wisconsin brothers says he believes a Missouri cattleman promised to give the men money to lure them to his farm so he could kill them.
Twenty-five-year-old Garland Nelson, of Braymer, was charged Wednesday with two counts of first-degree murder in the deaths of 35-year-old Nick Diemel and 24-year-old Justin Diemel, of Shawano County, Wisconsin.
Rob Chubb managed the feeder cattle side of the business operated by the brothers.
Chubb says he is angry, but that he knew from the day the brothers went missing that Nelson was involved. He says the brothers had done business with Nelson in January, and that Nelson owed them money.
Court documents indicate Nelson owed the Diemel family $250,000. Authorities haven’t said the brothers were lured to the property.
I have not seen any actual documentation from either Diemels Livestock or from J4s concerning the $250,000 figure other than the father's claim that JN owed them $250,000 for cattle. I would love to see the books of both operations but that won't come out until trial most likely. My hunch is that the two sets of books won't jive on the amount owed or to whom. Others who know the cattle business have openly questioned that amount of debt on the number of cattle that we know were involved. There is enough evidence in the public arena to know that JN played fast and loose with his business dealings. He not only owed Foster (in Kansas) for cattle but also for a metal building and refrigerated trailers. It is very likely that JN had other side deal or deals not on the official books. Some likely with ND & JD. If the $250,000 were about cattle it had to be more than those involved in the Foster deal. Since some of his known side deals were not specifically about cattle, it is possible that not all of the $250,000 was about cattle.
With $250,000 missing I would say that there is probably a money trail to be followed. I am not sure exactly where it will lead.
I can give you some dots to connect for yourself if you care to. These do not prove anything, but offer a possibility. Public record connects this story from the Green Bay area to Milwaukee to Kansas City to Eastern Kansas. If you literally carry that line from Milwaukee through Kansas City on a little farther south you end up in Oklahoma City. Ask two questions. What other business besides cattle has all three locations in common and could account for a $250,000 dispute that ended in murder? Are there any news reports on the internet that connect the two businesses?
I cannot say with certainty that either ND & JD or JN were in a business other than cattle. I cannot say that they weren't either. I believe what we know AND what is not clear both lend themselves to the possibility somebody was into something besides cattle.
I have now very unsatisfactorily answered your questions.
I do want to be absolutely clear about a couple of things. You are absolutely right in that, no matter what, the murderer needs to be held accountable to the full extent of the law. IMO JN is guilty of some part in this. Possibly everything that he has been accused of. I hope that the whole truth comes out and he gets everything that he deserves for everything that he did.
But, as I have stated before and probably will again, this story did not begin with July 20 & 21. Something led up to someone killing two people. We need to know the backstory on all parties involved before we know the truth. It may be as simple as the story told by the affidavit - A crime of passion or desperation. With the FBI, USDA, US Postal Service Inspector General, as well as local and state LEOs involved in the investigation it may be a lot more complex.
No amount of backstory will bring back two dead men. Nor will it heal two shattered families. Justice needs to be served. But the full context may shed a whole new light on the events of July 21. Depending on what that context is, we may not get the whole story for years, if ever.
sbm No prob, easy to miss. To remember that $ amt, I had to search the Wayback Machine in My Brain (so much useless info there in the WBMiMB, going back several decades to grade school and now clogging up the place 
). Then had to dig around more for the link.
