I don’t think he embellishes either but throughout the PC he continually used words like “may”, “might”, “could” to indicate a possibility..as opposed to words such as “I know” or “we’ve confirmed” so I don’t think anything he said can be assumed to be beyond the classic profile of a suspect in an unsolved case. It’s well known from prior solved cases that guilty people closely follow news of the crimes they’ve committed. I’d imagine it comes from necessity, much for the reason Carter stated “he wants to know that they know” in order to avoid getting caught. Active interest in this case was also one of the several characteristics the FBI put out early, a list of suspicious behaviours to watch out for (including changed appearance, unexplained whereabouts on Feb 13th, etc)
I do think it was intended Carter’s presentation during the PC be highly dramatic. Many PCs have already been held in the past 2 plus years and the risk is that people become tone deaf to the same prior theme of requiring that one tip, so it’s purpose was to to shake people awake IMO for a couple of reasons -
- to take the emphasis away from the prior sketch of national focus which had been strongly promoted by LE to be the face of the suspect for almost two years now. Instead to invigorate people in and around Delphi by zooming in on a suspect who had local connections.
- to unsettle the suspect, hoping that somebody might be able to observe suspicious behaviour that would result in that “one tip”.
