That's a lot of new info, considering how little we learned from the media so far. I hope the police gets closer to solving Prisma's case by publishing this.
Quite a few things Prisma did that day seem puzzling.
In the video in the restaurant she looks to be alone, so I assume her ex left earlier than her. Why did she stay and not return to work? One of the three hours there was probably spent talking to her babysitter.
Did she know the person she was in a road rage incident with after the restaurant visit? Who called 911?
Where was she heading when she turned onto the interstate? Why did she turn back? Was she on the phone at the time?
The pedestrian door to the Olympus garage in the new video looks closed, so she entered through the car entrance after a car drove in. Since she stopped in front of the elevator, she probably had no connection to that car.
In one of the early news videos a police detective is heard saying "once she gets in/on the elevator" in the background of the reporter's commentary, but the reporter never addressed it. I found it strange at the time. So earlier we were speculating that she went deeper into the garage or into a car when she turned around the pillar, when in reality she took the elevator up. Why was that part not shown/mentioned before? Because there was another person (a stranger?) in the video?
Apparently it's known on which floor she exited the elevator (one floor above from the other person). Was it the top floor? Was she seen on camera on that floor? At what time did she exit the elevator? How long after that did the last (after 5:57) phone calls start?
We learn from the video that her phone last pinged at the Olympus. Was it turned off immediately when the calls stopped (at 6:01)?
