So let's get this straight KJ.

They both reported sighting you at different casinos, and you thought at the time they had sighted you, but now you realize they hadn't?

Were these reports years after the fact? Because if someone says they think they saw me at some random casino within a reasonably specific time frame, I would know whether it were possible, and if it weren't me it probably wouldn't be possible that it was me. (I.e. dates times and details wouldn't line up.)
