Dear Ms. Lam,
Thank you for posting your request on History Hub!
The National Archives does not have copies of state court records. Please contact the Superior Court of California, County of Los Angeles’s Archives and Records Center (ARC) for information regarding this case.
We hope this information is helpful. Best of luck with your family research!
Thank you both for your reply. Sadly I phoned and emailed them and they say they destroy records after 10 years, which I'm still quite sad about. And it seems like a lot of history is being lost that way.
I might contact the DA office on the off change they have any information, but it doesn't seem likely.
