The next day, tox screens came in showing what toxin was added to the dead man’s drink during lunch. Tony also found information that painted the man as a player. Married with three girlfriends on the side. Of course Caitlin didn’t appreciate his musings about how the man had four successful relationships at once. Gibbs rightly corrected him, three successful and one very unhappy relationship. In fact it was the unhappy one, which the dead Marine tried to break off, that led to his death. Seems girlfriend number three didn’t appreciate being dumped the week before the fateful lunch. Insisted on a second meeting and poured poison in the man’s soda when he stepped away for the head.
