Under Contract no longer answering calls

[Luis Magnus]

Hello everybody, I am 2 steps away from closing my first deal, I have it under contract and everything but the title of the house is under a Living Trust, when I escrowed it at the title company they asked me if I could call the owner back to find out if he has a copy of the trust or a will. 

The house belonged to the guys grandmother who past away, during the appointment he claimed that he was the only beneficiary and that the house was his and he had been living in it for over 25 years. 

Long story short, He is no longer answering any calls, texts or E-mails. It has only been 2 days of calling him multiple times but there is absolutely no response at all, I am scared he is looking to back out or something and I don't know what to do, I even skip traced him but there is nothing I could find. 

I am seeking for advise or any solutions, maybe there is a way to search for a copy of the trust that I don't know about. PLEASE HELP!
