Does anyone have confirmation where her body was found? To the neighbors, you would have seen a white van, most likely, and perhaps forensics. My hunch is he lured her in, did the unthinkable, had a plan in place to dispose of her, but the police acted so quickly he may not have been able to act on that plan. Or...he did act on the plan (wheeling her out in suitcases, driving to a remote area), and they were able to find her - or he told them where she was.
Since he plead not guilty, I'm leaning towards he wasn't able to take her body away from his residence. They had hound dogs on the scene pretty fast.
As a reminder, I think the reason the police were able to act so quickly is because her FOB showed her locking her apartment door at 6:30 AM, like she always did, but then her phone turned off at 7 AM, and her car remained in the parking lot. Colleagues at the search told me she *always* drove to work and she was never late.
So the police were like, okay - she locked her apartment at 6:30 AM, but her car is still there, but she isn't seen on cameras leaving the apartment building - she's gotta be in there with some nut job. Good instincts by our police to take it so seriously and not assume she 'walked away' somehow of her own volition.
