Please help me with this:
What do we really know about KM's "work" in As' dental office?
If you go to their website, you will notice it is really elaborate, with a detailed roster of its staff, including the clerical assistant staff. The website has been so elaborate for many years, including well before and through 2014. (Use the Wayback machine and click around for all of the previous years.) You will notice that the staff page never contains KM's name.
Now there are only a few possibilities: One, that she was such a temp so that she was never featured on the website, or she was featured briefly and taken down, during a short gap so it was missed by the Wayback machine. The other possibility, I think, is more nefarious: that her "work" was a money laundering front. Of course, it's possible that her "work" was so minor so is to not feature her on the website, but this seems implausible given that there are other assistance and clerical staff his names are listed.
I have tried to Google the news stories talking about her work at the dental office. And even though this fact is mentioned all over the place, I can't see anything noting additional information about, eg, when exactly she worked, how long she worked there, in what capacity she worked there, etc.
