I don’t think KJ’s phone showed EC what route KJ took. EC was using the Find My Phone feature which showed her where KJ’s phone was, which was just inside the CA & 10th St entrance. I believe that EC has indicated that she entered at CA & 10th and very shortly saw what turned out to be Bowie. Also, JMHO, I don’t think KJ would have walked along the parallel path to 10th; too dark. I am not convinced APD would or has released CCTV video of KJ or EC entering PP. I don’t think the APD wanted or still want the timeline public.
Well as far as I'm aware, they have that app where you can see where the other person is at all times. For example, EC could look on her phone, and see that Katie was not moving, so that means she's getting real-time data of her movements. I don't have that app, so I don't know if there's some historical feature, where you can go back and trace where they were.
-- As to what path Katie walked on 10th, she clearly crossed over into the park path, at some points before Charles Allen Gate, because first, she wasn't caught on Charles Allen gate cameras, and two, she ran into the park. If she was coming from the Charles Allen gate side, she would have ran out of the park.
And I believe somebody on here mentioned that there were several cameras on 10th Street that should have caught her walking on 10th Street. So that implies to me she crossed over into the park shortly after the rainbow crossing. And walked on the parallel park path. Yes I agree that kind of seems odd that she would walk on an isolated park path at night. However that path is literally right next to 10th street, within feet. So I'm sure that makes it feel safer.
The fact that she chose to walk on a isolated Park path, instead of on 10th Street, further supports the idea to me, that she was purposely trying to hide what she was doing and where she was going. I think it's possible that whoever she was trying to meet, specifically told her to avoid the cameras, and not to go through Charles Allen gate. She of course, thought he told her that for one reason, but of course he had a whole other reason in mind.
