Probate not filed?

[Lyuba Barrington]

The investor I am working for (as REA) was interested in a property which, he noticed, had not been mowed for a while. After some googling I found out that the owner has died in 2008. So I figured he died intestate and the estate has not been settled yet. I am calling the county court where the property is located and they tell me that they cannot locate the case under the name of the deceased... Looking back as far as 1985... Any ideas what can be done next?

The old obituary says that the person died in different city/county (same state) and also that all his relatives live in yet another city/county. Does it make sense to call all other places?
