Sure there is. Was he murdered? Who knows? The conspiracy nuts, however, don't help. Some even use the absence of evidence as 'evidence' of a conspiracy. Then again, perhaps I'm not open-minded enough to believe that a birthday card plugged into the Bible Code will solve this murder.
The standard reply by everybody in the 'Toon administration questioned about anything illegal was "There is no evidence." Great parsing of the English language.
I assure you I am not nuts. You just don't know the facts. A dumped body, found in a park, is prima face evidence of murder. In fact there in no evidence for suicide: (virtually) no blood, no bone, no brains, no bullet found associated with the victim.
If you are really interested you will check out a new thread, The Vincent Foster Op-ed Contest (Redux), I started about this.
