I need to find someone who owns a domain name my company wants to purchase. Of course we have all of his information including email and phone.
The problem is the guy is choosing not to respond, or maybe he died

.
The domain is registered through godaddy.com.
Sooooooooo how do I find this guy? All conventional attempts have failed and I am thinking there must be some sort of way of getting to him through godaddy.
My last resort may even be to subpoena him for violating a copyright or something along those lines. Again that is a last resort.
This would make me look very good to my company........very good.
We are willing to pay for this domain name and any help would be greatly appreciated.
