-Did Barbara in fact take a 360 photo? With what, her phone? His phone? A camera? iPad?
Don't know conclusively. My information says Barb has no phone.
-Did they stop anywhere before the spot where she went missing?
I was informed they'd been here many times by Rob's family, then I was told it was their first time here, by Robbie. All accounts from Robbie, first and second hand, cite a nearby cave which Robbie 'returned' to, to look for Barb after not finding her at camper.
-Was the photo of her in news stories taken the same day she went missing?
MOO The photo of her in bikini with hat and glasses was not taken the day of her disappearance, but is the closest photo Rob could get hold of that looked how she looked the day she went missing. As I mentioned this fits with what I know of her 'stroll through desert' style as well. Photos from the day are likely still in law enforcements hands, assuming he had an actual camera on him, and was not just snapping photos with his cellphone.
-Did they always get along?
In my experience no one always gets along. They're both very human, had arguments and were able to get through them. My father and his wife refer to their arguments as comical and a notable part of their relationship. ie. It was entertaining watching them stubbornly bicker over something.
-Any financial struggles or recent life changes?
I also would like to know this.
