I would guess yes. Especially P3. And P2 as well. That cam view from c2 doesn't seem to extend far, with the lights off, and perhaps some doors open and obstructing the view as well. We do have to recognize that this is indeed where she went, starting at SW corner doors and moving northward up that main hallway, and perp was somewhere up there per LE. Maybe she was hit or grabbed and taken out of hallway, as well.
PS - Since LE swore under oath "The video shows Terri Bevers walking toward where the suspects location. Neither the suspect nor victim, were seen again on video", then we can trust they don't have any video of the actual killing. A lie would jeopardize the case and subject someone to a perjury charge.
