<p>It was reported that Clark sent an email to Annie Le and she replied his email right before that deadly meeting. If they did meet in a semi-private meeting room, which we may find at many working places, I would guess there is a slight chance that he may be able to control his rage in such a way that he might not kill her during the meeting, or somebody may happen to walk by the meeting room and report or intervene it.</p>
<p>Here I assume that at the beginning of the meeting, Clark really did not have any intention to kill Annie Le. If I am allowed to make a guess, he himself did not believe he would commit such a crime; he was just “out of control” at that moment. A change of environment (e.g., to meet at the cafeteria in that building, if such a meeting place exists) may cool him down a little bit. – I know I am like a Monday quarterback here.</p>
