I know this has been discussed here in the past but I can't locate the old thread. Anyway this update appeared in the NYT. It is unlikely to satisfy anyone who has studied this famous incident or speculated on it in the past. I've always found it to be a fascinating mystery and one that is unlikely to be definitively "solved" anytime soon, if ever.
