How else can you find out where someone died besides the SSDI?

Question:

How else can you find out where someone died besides the SSDI?

The SSDI has where he last resided. He did not die there in Whiteside County Info: Keith E Miller DOB 01/10/1958 DOD 09/21/2005 I need to know where or how he died. Can you help me? I have tried looking for obits but have found none. I have checked in all counties surrounding Whiteside and they have no record of his death. Father name Harold Mother Shirley Both dead.
I don't know the state of his death and I don't want to have to pay each state just to find out. That could add up to $100's of dollars. I can't afford that. Help!!

I did not find out he died from a relative. I found out through the child support office where I live. My daughter now recieves survivor benefits but I just want to know how he died really and if I could contact any of his relatives that would be nice. Yes he used to live in El Paso, Tx but he left here in 1990 and I didn't hear from him since then.
