My random thoughts on this case so far:
I know some think, after so much time and not having found her yet, there's no way she would still be alive. But, there are countless stories of people being held captive, and presumed to be deceased when they were not. After 19 days, search warrants, impounded vehicles, interviews and on and on, there still has not been an arrest. LE would not hold off if they had the evidence to move forward.
Many theories revolve around "how it happened", and attempt to fill in the gaps with what could have happened. Were there eyewitnesses that saw ZV come to RF's house, and enter the house? Could something have happened to her earlier, before they supposedly ate dinnner at his place? Maybe there was some activity prior to their "date" at his place. Her car was at his house, and at some point it was moved back to her house. Wasn't RF the only one to see her, that we know of, during a long period on Tuesday? She was "last seen" by RF, correct?
For me, there are still too many gaps to be able to piece together what happened. Is it 100 percent confirmed that she was the person at RF's apartment when it was reported they were cooking dinner and the neighbor could smell food cooking? What if it was someone else? Where was ZV's car parked at RF's apartment? On the street, in the drive, around the corner, etc? At what time was she supposedly seen with a man on camera at Stripes? Could this person (someone other than the known POIs and suspect) be the one that took Zuzu somewhere, and some of the other events later might have been setup or staged? I know I'm reaching, but I'm just trying to come up with alternative theories as to what happened. I'm not discounting anyone's theory, but just adding my own thoughts to the discussion. Many aspects of her disappearance just feel too "neat and clean" for me. I feel like there may be other actors involved, who so far have not been identified.
To me, the warrants that were put out do provide key details, but some information is intentionally or inadvertently vague. There are good reasons for this, and all that is needed is for a judge to be able to okay the warrant.
There are too many gaps that need to be filled in, and not enough information is out yet to do that.
I hope LE are monitoring these POIs. Wish they would come forward and tell what they know about this case.
