I’ve been lurking... after watching that video, I 100% think she was drunk. I wouldn’t say that if me my friends and loved ones didn’t drink as much as we do. I think there is a likelihood that she went to a lunch and decided to order drinks- whether to celebrate her new job or get friendly with new coworkers, or maybe to increase her confidence/courage in something she was about to do? I really really want to know what her phone conversation was.. I’m sure LE knows after interviewing but she surely must have said something pertinent while she was “waiting”
I believe their next order of business would be to conduct a search in the whole building, door to door with dogs, and ASAP. Her scent will point the direction of who might know where she is or what she was there for..
