MeanMaryJean, I'm quoting your post, but not picking solely on you, as I think others are wrong about this as well. There are at least three reasons that readily come to mind why these companies might cover up a rape and murder by a driver: 1) to avoid losing a multimillion dollar law suite. 2) Kugar might want to cover it up to avoid loosing Corona's business. 3) the driver could be a relative of the owner or senior management of Kugar or one of the other companies.
Employers are very often held financially liable for the actions of their employees. McDonald's had a judgement against them for 2.86 million dollars because one of their employees handed a cup of coffee to a woman and then she spilled it on herself. The coffee was very hot and hurt the women...who had spilled it on herself. 2.86 million dollars...that was for a hot cup of coffee.
If JR and his team didn't have credible witnesses to Jenny being picked up by the 'Corona' truck, the police would never have brought a driver in for a polygraph test and Kugar would not have released the GPS log(s).
That the suspect truck was sold and never located for a forensics test, in my opinion, speaks volumes...
If the truck is now located, a year on, and a forensics test done which is reported as being negative...too late, they have lost all credibility.
You always make such good points, webant. My brain is running on empty today, so my thoughts may be way off in addition to being lengthy, but here goes.
I think it's quite possible that Corona did pressure Kugar to cooperate. I just doubt they'd go to the extent of threatening to dump Kugar as their transportation company (as I discussed with Dex) without much more info. But maybe they have that info and did apply pressure. Or, maybe Corona and/or Kugar stonewalled for any of your three reasons or another. JR's recent allegations of sex trafficking make me wonder if that's the compelling reason for a cover-up.
For a while, both companies were cooperating with JR according to his account of visiting Mexico. He was optimistic. I think it's quite possible that LE got access to the drivers because of employer pressure on the drivers, and the pressure certainly could be due to an abundance of evidence/reasons we aren't aware of. Or, LE may have gotten to the drivers without corporation help. JR may not know or hasn't told HFJ exactly when or how the polygraphs came about. His intensely negative focus on the corporations implies that they are somehow involved in covering things up, rather than cooperating. But JR has a history of being highly critical of anyone who can't or won't help him (the U.S. Embassy, his congressman, the Chinese Embassy, etc) so I take his opinions with a grain of salt.
I honestly don't think the possible threat of a lawsuit would intimidate these corporations. Could JR file and win a lawsuit in Mexico? Or would the justice system there grind him to a pulp. I'm doubtful he could prevail unless there was something going on that was waaaay bigger than Jenny.
The McDonald's hot coffee lawsuit really wasn't about an employee acting improperly. It was about the standard McD temperature of the coffee causing third degree burns and getting compensation for expenses. The $2.7 million was the amount the jury decided against McD for punitive damages. It was significantly reduced after the trial. However, there certainly are cases in which a corporation has been found responsible for employee misconduct.
OT: Public opinion about this case has always bothered me. Many people think this case is the poster child for frivolous lawsuits. I strongly disagree. It's worth reading the Wikipedia account, at the very least, to understand the whole story. For starters, all the woman originally wanted was the modest amount of $20,000 for medical and related expenses. She very likely would have accepted less. McD offered $800, first and final offer. Hence, the lawsuit, which could have been settled before trial. Read on....(not trying to debate, just present more info that IMO has been overlooked by the public).

Apologies for going on and on and on. I'll try to edit better in the future.
