Seeking criminal record of Raymond Demonbreun

My father was Raymond Patrick Demonbreun, DOB 1-6-1932. He was born in Chicago, IL, and his birth certificate lists him as "Ray Demonbreun". I found his father's obituary, Robert I. Demonbreun of Nashville, TN, which listed Ray as living in CA. When I researched further I found newspaper articles of 1963, about a murder in Hollywood for which Raymond had been arrested in San Diego. He was sentenced for manslaughter and given prison time of 5 years to life. There was also mention that he had been recently released from prison for burglary. I am looking for his criminal record in California during the 1950-1970 time frame.  I was never able to meet him and have no pictures or personal information. I would really like to know more, even the bad things, about the missing half of me. Please let me know if this is something you can supply to me or where else I can look. Thank you very much.
