Theorising - the video footage that we have as provided by msm - is of a male and female walking into the entrance of a parking garage.
We now have been informed from what I've read up thread, that other cameras were working.
Perhaps these 'other cameras' recorded these two people separately, perhaps not. We can only speculate.
If LE were to release later footage of the female walking alone, IMO that would set fear into the hearts of all young woman in the area.
This would suggest to me that IMO - LE released the particular footage that they did, in order not to create panic in the community.
We know further, from earlier reports up thread, that Christina's phone did not record anything beyond the Legacy shops area.
That then suggests to me, that if there were any further footage of her on record then it will be in close proximity to the garage and shops.
LE also reported (up thread) that she didn't head south of Legacy (after the video footage). It is of interest to me that LE should especially indicate 'south'. From my experience here on WS, LE do not tell us any more than they absolutely have to, or will work to their advantage (as we would expect).
That indicates to me that if LE have footage of Christina on foot and alone - it is either in the garage, or perhaps an exit on the northern side - I think that's where 2 vehicle exits were.
