Property with no owner?

[Jesse Anguiano]

Found a property and whom I assumed was owner but after speaking with him. He states he nor his father ( same name) have ever resided at this property. After scouring records and search engine sites for other possible leads even children so that I could execute a affidavit of heirship yet it all seems to point back to this man. Only thing I can think of is he wants nothing to do with the property? Is there anything I can do other than find the actual owner or rightful heirs?
