Hi Marsha, He officially died in Los Angeles Co. per the California Death Index.
However, searching for his obituary in Lucerne Valley, San Bernardino or Glendale, Los Angeles are reasonable places to start.
The Glendale Public Library, library.ci.glendale.ca.us/central.asp does have obituaries.
If they don't have his obit, contact the Los Angeles County Public Library. I've provided their access info in previous replies.
Then I'd try the San Bernardino Library and I've provided their access info in previous replies.
If the obituary doesn't have his burial info or if you can't find his obituary, contact the Los Angeles Recorder, http://lavote.net/recorder/BDM_Records.cfmhttp://lavote.net/recorder/BDM_Records.cfm . Successful Searching!
