Yes, all of these D.A.gon(e) jokes are so bad, I hesitate to dignify that fishy alphabet soup with any actual comment. The simple matter of fact is that the District Attorney of San Francisco at the time, in 1950, was none other than Pat Brown, who went on from there to become the Attorney General of California, and later Governor of California, so I don't see that he was fired. Even so, he eventually died, in 1996. No one ever said that the prosecutor was fired.
Even so, the facts of the case as they are presented in the only documents available at the moment seem somewhat Spartan and lacking in context. If you didn't want to buy it, why did you give the money in the first place, or else you changed your mind and demanded a refund, or else how did the assistant Mr. Longwell assistant get his hands on the money without the permission of Mr. Schmidt, all of which begs the question, why is this petty complaint pending in the criminal courts? If you died while on probation, can there ever be a satisfactory answer to the complaints of either party? We cannot bring the parties back from the grave to continue their conversation. We must rely on what few written documents that are available and may have survived the backyard fires over the years, if any may be found.
