I'm still convinced the Rs were mistaken about those dates. It's just impossible they knew at that point.
Other than being mistaken, which I find hard to believe as well- how do you mess that up when you know you are talking to the media?- could it be that KK called her bestie MS and started talking to her right away? I don't think they found out through a facebook post- there werent' any.
And then MS was so upset she started laying the foundation with the R's. Telling them she heard that the woman PF wanted to kill has gone missing. KK is so upset? That is kind of what I think. Not sure we will ever find out that end of things though, don't think anyone will focus on the R's after all the info comes out.
