If LE has any sense, they'll give us something. While being great at stonewalling and very shifty with words, Winker also seems like a pretty intelligent guy. I think he realizes if they give us more word salad, many casual observers and MSM will lose interest.
One theory I heard on Grey's broadcast was that LE purposely has been having the parents & DJ say varying things on TV and releasing varying accounts because they definitely have a POI and they want that person to either relax, get confused or slip up. At this point, I don't think anyone outside of the investigative team can confirm a reasonable timeline on the night MT vanished. At some point, if they want public and MSM to keep helping, they're going to have to show some of their cards.
