I have not been particularly attentive to the world for bridge for the past few years, but this is something that I think would have been widely reported if it were true. This is the first I have heard of it. In fact, I vaguely recall there being some mention of disappointment that there was no statement left to be read after Schapiro's death. For what it is worth, Schapiro's wikipedia entry makes no mention of a posthumous admission. As I mentioned a lawyer said it. Maybe it wasn't official but the bulletin where it can be found on the internet (maybe could have been found) had the statement and, if I'm not mistaken, Truscott's reaction.
