Beverly Katz looks at Brian Zeller out of the corner of her eyes, during the investigators' meeting.
Back in part 4 of the analysis, we went into some detail on the microscopic characteristics of hair, and we concluded that the woman who did the analysis of the hair found on the tissue note found in Lecktor's cell, Beverly Katz, was in error when she claimed that the hair sample must have been from the Tooth Fairy. Recall that when Graham and Crawford start walking the tissue note and hair samples (which have been flown in from Baltimore) through the various analyses, they first visit Katz, and Graham supplies her with hair samples from Lecktor's comb, hair from the guard who carried the note to Chilton, and whiskers from the electric razor the prison staff allow Lecktor to use. Katz looks at the tissue under a microscope and states that there is a half-inch long blond hair on it. Later, after all the analyses have been done, there is an investigators' meeting, and it is during this meeting that Katz confidently states her conclusion that it was the Tooth Fairy who wrote the note. Shortly after she makes this statement, Brian Zeller (the fibers man) says that nothing of any help was found on his end. Then, a call comes through about the ad Lecktor has sent to the Tattler. It is at this point that the camera focuses in on Katz, and we note that she looks at Brian out of the corner of her eyes, and he looks back at her, as if they share some 'special' knowledge.
The likelihood that Katz's error is an honest mistake is extremely low, when we consider that she is an FBI expert hair analyst, and that it is, in fact, the book the FBI itself uses (Butterworth-Heinemann, which was quoted in part 4 of the analysis) that says microscopic characteristics of hair alone, cannot be used to positively identify two different hair samples as having come from the same person. What must be the case is that Katz is involved in some sort of plot to deceive Will Graham. This will be explored further, in subsequent posts in the analysis.
