My guess is that Cheshire does not want any statements to be lost. Timing is going to be important. I assume that we will see more vocal activity as we get closer to the next milestone set by the court. The exception would be the emergence of a "smoking gun" that could potentially blow the case out of the water.
Maybe the info about CGM having had sex around the time of the incident with her boyfriend would have shut a few people up and calmed the race baiting a bit.
... like the cell phone data, if it still exists.
