Disagree. I think foreclosure would be his best and the only good outcome. He can not sell the property. The land is completely destroyed and looks like they could shoot the next moon-landing movie on it. There is no topsoil, no nothing. And even worse, there are several hundred carcasses buried in very shallow mass graves all over the place making the place a serious biohazard that potentially could contaminate the ground water.
Whoever owns that land will be responsible for the cleanup.
Best outcome is forclosure and the ranch and responsibility for cleanup becomes someone elses problem.
