Recall that in part 5 of the analysis, we discussed the lecture given in Atlanta, on the cast of the Tooth Fairy's teeth: we said that the man giving the lecture, Dr. Dominick Princi, said that the Tooth Fairy had pegged lateral incisors, but he pointed to the canines while he said this; it as if he was indicating that they are the lateral incisors.
Princi was intentionally misleading those in his audience (the Atlanta police officers, and Will Graham and Jack Crawford). By pointing at the canines, which were the most prominent teeth in the cast, he was intending to imply that pegged teeth are abnormally prominent (i.e., abnormally long). Thus, anyone (i.e., Graham and/or Crawford) who had heard Princi speak, and had, on some other occasion, viewed the teeth marks in the tissue note, would not have thought there was any discrepancy between the marks, and what Princi said about the cast, since the canines are normally the most prominent teeth, and the most prominent indentations in the note are from the canines. If a lateral incisor had been pointed to by Princi while he was speaking, and anyone had noticed a discrepancy, i.e., that the bite marks in the tissue note did not indicate the killer had pegged lateral incisors, whereas the cast indicated that he did (pegged teeth being, in reality, underdeveloped), doubt would have been raised in one or more investigator's mind as to whether the marks in the tissue note were from the killer's teeth. Princi said and did what he did during the lecture to mislead his audience, in order to avoid any such doubt being raised; thus, we see that Princi is involved in a deception.
