Hello Everyone. What an interesting discussion. Like others, I was drawn into thinking about this case after viewing the very odd elevator footage. Although many issues have intrigued me, I would like to focus on one that I've got some questions about.
Where are her glasses? Have they been found, and, if so, where? As a near-sighted person, I would never travel without my glasses. Most glasses wearers undoubtedly do the same. Even if you wear contacts, the glasses are still a backup. I'm assuming that Elisa traveled with her glasses.
1. Did she leave them in her room? If so, I think she planned on leaving her room for just a short time. Maybe she was going to the bathroom, and perhaps the one on her floor was dirty or occupied, so she went up to the 14th. I'm assuming she was not staying on that floor, since then she would not be trying to take the elevator down, unless she wanted to get to the lobby because of a problem. Or she was sleepwalking.
2. Did she leave them on the roof, or possibly lose them there? If she was there with someone and things got creepy, she might hurry off without them. Or if she lost them, she might go to the lobby to get help in finding them. But then why would she press all the buttons? Even if she could not see them, she would know the lobby buttons would be near the bottom.
3. Did she leave them in another hotel room? Possibly on the 14th or 15th floor. If she was interested in and flirting with someone and things turned unpleasant, she might choose to leave ASAP and just leave her glasses.
4. Did she leave them in a shower room? If she got spooked when preparing to take a shower, she might have abandoned them there.
Or was she wearing contacts during the video? That seems unlikely because of the way she bends down to make out the numbers on the elevator buttons.
I guess there is no way to tell, but number 1 or 3 seem most likely to me. Any thoughts?
