I'm confused. Didn't MB originally say she left for JR's because she wanted to party ... and then it became he escorted her to JR's? And now she left while he was upstairs, according to VS? So which is it? To top it off, wasn't MB supposed to be the one who wasn't partying?
There is 3 different versions (that I know of):
a) MB helps CR to bed, LS asks him to party to which he declines, then he sees her walk out (sourced originally by CR's lawyer and was the general story through much of the original media coverage)
b) MB helps CR to bed, LS is gone when he comes back downstairs (sourced by Indianapolis Monthly by way of neighbor, VS who talked to MB)
c) MB helps CR to bed, decides to turn responsibility of her over to JR, calls JR, walks LS over to JR's, LS asks him to party to which he declines (sourced by Lohud by way of PI's who interviewed MB)
There is also a version that MB would have given to LE shortly after the disappearance, which may or may not match one of the above.
