Shortly before he left for lunch that day, he got a “head’s up” call from someone informing that the FBI had just removed documents from Madison. I am at work and don’t have the references at my ready, but if you check the story line, you will find that the same day Foster left this earth is the same day that the FBI entered Madison.
By the way, it is not unusual for a person considering suicide to “give away” things...thus I don’t read giving M&M’s away as a sign that he was not more depressed than usual.
Hmmm....I wonder how they reached him. IIRC his car was never “signed out” of the parking lot when he left for lunch.
