Unsolved, my fanny. Hillary had him murdered.
I would agree that she is a hot suspect. Conveniently for her, she had a ready alibi: she was out of the country in the Orient and Hawaii for a couple of weeks before the rubout. But it's more than irony that she arrived back in Little Rock on the afternoon that the body was found in FMP. This gave her the opportunity to direct the cleaning out of documents from the decedent's White House office by her loyal acolytes.
