"Before the CityLife Hotel footage emerged, the last confirmed sighting of Grace had been CCTV of her dressed for a night out as she left the Sky City casino complex at 7.15pm.
She was wearing a pink £5,000 prize draw wristband, suggesting she planned to return to the casino, just a few minutes from the hotel."
More information about the pink wristband. And the CCTV is from the casino, so they obviously did have CCTV of the hotel but haven't released it. And apparently they don't have CCTV of her leaving, but are still looking. Going to look back through this thread as there was some discussion of an underground car park I think, which seems relevant now. They have also identified a 'vehicle of interest'.
Hopefully they will be able to put pressure on this guy to reveal what he has done and he will not leave the family in misery.
