A friendship ended over a cattle deal just a few weeks before two brothers from Wisconsin went missing. Nick and Justin Diemel had been visiting a cattle operation near Braymer, Missouri. Police say they'd been in business with Joey Nelson who is in jail on tampering charges. Court documents state he dumped the brothers' rental truck. Police later found human remains on his farm. KCTV5’s Nathan Vickers has been looking into Nelson's past dealings.
