He died on July 20, 1993.
With reference to the innocents in Boston controversy about Mueller writing a letter, the last I read was there was supposedly a document that disappeared from the National Archives. Surprise. surprise.
Anyway, I think it was documenting that Hillary had read Foster the riot act in front of all the others at the meeting. I thought I read that in World Net Daily which pointed to an appendix in, I think, the Wash Post.
It's hard to pick up the pieces of a "cold" (for me) case because I didn't start reading about the details until quite a bit later.
It does come across as fishy on several fronts although his family hasn't disputed the "official" story.
