I think quite a few pictures may have been scrubbed from the internet, perhaps by court order. They were trying to keep the facts under wrap while they talked to a widening circle of people to see if there was independent corroboration of the timelines given by the phone(s).
It was probably difficult enough for an investigator to get the timeline clear in his mind. Since LE definitely shifted from "last proof of life" on Friday, to Saturday/chipmunk hunting time (because JL provided a new time parameter when they finally talked to him), they wanted to remove pictures that might have allowed weirdos (and others) to insert themselves in the case and say they saw either Suzanne or Barry at such and such a place. Real witnesses needed and in every case, there are people who will try and become "insiders" using even the slightest information.
The weird thing is that at the prelim, IE insisted that Suzanne took the picture of Barry at Moonlight Pizza and sent it to the girls. But it's possible that Barry had control of Suzanne's phone at that point. OTOH, there was no reason for the State to dispute that Suzanne was still alive that evening.
Lauren Scharf reported that Suzanne was at home, on LinkedIn, communicating with JL during the time of the alleged pizza run, and that Suzanne told JL, "He's gone for a bit."
She likely would have been on her laptop for that LinkenIn wifi-based communication. It's possible that Barry grabbed her phone (which would have had to be unlocked or bearing a password that he knew). I think that's farfetched too. I wonder if Suzanne's actual phone records (from their carrier) show her going to Moonlight Pizza or not. Indeed, I don't think IE said whose phone was used to send the Moonlight Pizza snapshot. She says "Suzanne sent it," but I don't recall that Suzanne's phone records were produced at the PH - were they? At any rate, Suzanne could have sent the picture via What'sApp (which would leave no trace, is my understanding). And were the girls' phone records ever presented to corroborate this? I believe one of the girls (MM1) said she received the picture - but I don't know what platform was used.
IMO.
(BTW, I did find the picture, I believe, of Barry standing in line to pay for the pizza; he's looking at his phone, not at the picture taker - Moonlight Pizza was doing only delivery and pick-up outside, no cash payments, so there should be a record of him being there - but I do not personally believe Suzanne was there. Maybe they were all using What'sApp to communicate, who knows. It is not posted on an approved source, though).
