[Jose Angel dominguez]

Any advise on this situation: 

I found a property but according to my skip tracing company the owner have being death for 19 years and the property have not been foreclosed, does not owe any taxes as of today and is not in probate. I can't find any heirs or next of kin and I would like to seek for any advise on this type of deals if you have run across one before and how do you deal with it?
