The've done exceptionally well at protecting and preserving Mary Katherine's recall.
This lady may be a good sketch artist, but she would have no idea whether Mary Katherine's recall was preserved or not.
The fact that it took the parents all this time to bring her in to do the sketch wasn't even mentioned in the Today Show interview.
Now we find out that Smart is the one stopping her from talking to the press, not the police. Who is running the show here, the parents or the police?
You might want to re-read the Boylan interview that Neenah posted. Boylan made it quite clear there was a valid reason why a sketch wasn't done earlier.
The parents and family, it would seem. They are, after all, the only ones involved with personal contact with the little sister and possibly the only ones who know of Elizabeth's contacts, friends, etc. ---- if the alleged abductor IS NOT a handyman, or a band of conspirators.
