EDIT: First of all thank you to everyone that has made a reply. I am sorry I haven't been as active as I wanted to be on this post. Just got some personal things going on. I wanted to clarify something I was wrong about. He lived in/last known address WS (West Sacramento) but died in Sacramento. He was actually buried in
"Camellia Memorial Lawn Cemetery Sacramento, Sacramento County, California, USA" (copy & pasted from FInd A Grave).

Another interesting thing on his death cert his race is listed as "white" when he was indeed Native American and was a member of the Navajo Nation. That doesn't pertain to my original post, but thought it was interesting nonetheless.

My dad was buried in a mass grave in West Sacramento, California. I knew he died but didn't find out until years later where he was buried. He was estranged but I had no idea to the point that no one would claim him. No, I didn't know where he ran off to. I figured he went back to the rez. Anyway, is it even possible to claim the cremains and have them exhumed? It would be nice to have him home again.
