How can I find out what cemetery a friend was buried at if I only know her name and DOB?

My friend ped away on 6-8-2008 and she was cremated and placed at a cemetery in San Jose California. Her name was Maria L. Vieira or its under Maria L. Melo. I am unsure. Her DOB is 8-18-1960. I was told she ped away in Sacramento CA but was placed in San Jose CA. Please help me find her grave. It would really mean a lot. Thank you.
