I think there's a good chance that CD and Lori are still in HI. I say still, because I believe that's where they went in late Nov., and because I think LE may have discouraged their leaving HI after their early (and perhaps only) communication with them in late Nov./early Dec.
My belief that they went to HI is partially based on previous posts regarding CD and Lori which alluded to HI, plus the fact that they were both familiar with HI. One of those previous posts indicated that after TD's death, CD was considering going to HI to grieve and begin writing a book. Another post indicated that before or around that same time Lori had posted on SM that she was looking for a dress that would be suitable for a beach wedding.
Plus, at the time CD and Lori left, I don't think they felt they needed to go into hiding. TD's body had not yet been exhumed, AC had not yet died, and Lori (at least) may have felt that either what she had done with the kids was legal - or that the kids would never be found. If AC's death was a suicide, Lori (and possibly CD) may have even known about his plans in advance.
