I tried calling the police to file a complaint for fraud, I tried DA's office and Texas Rangers, and No one gave me a satisfactory answer other than to pursue a civil case against this man.
Nothing in your post suggests any fraud occurred, and the mere failure to repay a loan isn't a crime.
I have a judgement against him and no power to collect
That the judgment debtor may be "judgment proof" doesn't mean you have "no power to collect."
This individual has no assets in his name although he lives royally...his big house is in a family member's name and businesses in another person's name - so he has all the qualification of a perfect con artist but I just cannot prove it and enforce any action against him.
I am really looking for some real advice how to recover my losses from him.
Not sure what you expect anyone here to say. If others are willing to support this individual in a "royal" manner, that's up to them.
Is there any other course of law that I can pursue that will force him to pay or if I can really prove fraud and send him to jail and maybe he feels threatened and come up with some payment to me?
You can try spending tens of thousands of dollars trying to investigate this person in the hope that you uncover something. Otherwise, this will be a very expensive lesson. When you loan someone money without any security for repayment, there is always a risk that the borrower will default and leave you with nothing.
