bbmI went back and listened to the new conference from last Monday Feb 2nd last night! link in THIS post
I am not sure if it was the same one, but listening to it now with what we know, I feel like they felt she was taken, and was alive when it happened but JMO
In the Feb 2nd SO News conference: One thing that struck me as odd was, it was at 9am local Arizona time and they were not going to continue to search the area. They had searched the day before and he said overnight too, and even had a map of the areas they searched close to the home. Is that odd to stop the search that early in? He said that if you think you see her, take a picture, take a video and send it in <<< I didn't find this is a normal thing to say if they believed she was killed in the home? It's been awhile since I have followed a 'missing' person though, so maybe it's just me.
IMO, it's highly likely she left the property in a car. and if you assume that, i think it means the immediate vicinity of the house is no longer a particularly high priority search area relative to anywhere else. she could be anywhere.
why a car? my understanding from news reports is that the trail of blood starts at the door, continues down the walkway, and then has not been detected (or at least not reported) beyond that. if it stops at the driveway or sidewalk, IMO an obvious possibility is that the bleeding person entered a car. besides, how far are you going to carry a 150 lb person on a sidewalk in plain view. and/or how far will you make a person with mobility issues walk under duress? again, in plain view on the sidewalk. ... what logical possiblities are left? helicopter? tandem bike? zip line? hard to picture anything but a car.
