I am with you completely. It’s going to be very interesting to hear from the two surviving roommates on everything being reported recently as well.I think there is more to her statement that hasn't been released. There are snippets of sounds she heard and I would be very certain that LE would have asked questions about hearing him leave, how long it may have taken him to depart, sounds of running water, etc. She may have even been able to indicate if any bath or kitchen towels were missing that may have been used to wrap an unsheathed knife.
Both roommates have lived in the house long enough to know if a bedroom was missing a pillow or pillowcase, which could also be used to wrap an unsheathed knife.
They lived together. They know so much not released to the public important to keep secret before trial.
