There is not a "scintilla of (forensic) evidence" that Foster died where he was found. At the very least, his body was moved.
And he ate the hamburger lunch at his desk before he supposedly left the White House about 1:00PM. I don't know if there are tapes, but an Arkansas friend (a young lady who was at the White House that day) called a friend in Arkansas that afternoon hysterically saying Foster had killed himself in the White House parking lot.
