I really think there is a correlation between LE giving continuous updates to the media, and an arrest in the case. I even have this new theory regarding it: If LE has no idea what happened to a missing person, maybe they even made some mistakes in the beginning, they are going to stay out of the media, because they don't want the case becoming high-profile, and have tons of pressure on them. On the other hand, if LE feels like they have a lot of the pieces to the puzzle, only missing a few, they are more likely to utilize the media. Why is it that in most cases, LE only talks to the media in the beginning? How many cases are they still communicating after one month?
