Hmmm....He ate lunch in his office, offered his M&M’s to his secretary Linda Tripp and told her he was going out for a while. That’s the last anyone saw of him. I don’t recall a disturbing phone call.
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.
