Many times the death certificate will list the name of the mortuary that the deceased was released to. If the person died in the hospital, they also would have those records, but due to the HIPAA privacy laws, unless you are family, they may not release them, or you may need to go thru significant paperwork to get the records. A moturary isn't bound by those same HIPAA privacy laws, so contacting them if you have the name would be the first place I would try. One of these resources should be able to tell you where he is buried.
Please let me know if I can help further.
I did some more research....and found his obituary. The funeral took place at Schoedinger, Hilltop - Schoedinger Hilltop Chapel 3030 W Broad StColumbus, OH 43204 United StatesSee map: Google Maps Phone:(NNN) NNN-NNNN The chapel should have records going back that they ca provide this information to you. I do wish there was more information available for Mr. Cox, but his death was very private it seems.
In case you need additional info, this came from:
Hopefully this will allow you to make a single phone call for this info.
