I do, too.As tight as the security is in that building, every movement she made was caught on camera. Do LE have that footage? Or, did H+F stall long enough for it to be deleted? I hope not.
That said, if H+F's key system is as sophisticated as has been reported, maybe there is a digital record of key fobs used during the time she was there. We saw evidence of that in Miya Marcano's case.
I still believe that something happened to her in that building.
I’m still thinking she may have gone inside a Service elevator on the back side of the building through that ally. I bet the security back there for moving in and deliveries is not so tight.
