After all this talk of the white truck, I printed off copies of the two surveillance photos, and I went down there to see which cameras they represented. (Someone on Websleuths may have done this already.) I took pictures, but I can't upload them now, as I'm at work. Anyway, the camera taking the perpendicular profile of the truck (the most seen photo) appears to be located on the north side of Morton Mansions, facing the south side of Tenth & College Village. The camera that took the higher, 45-degree angle shot appears to be a few feet west and across the street, attached to the south-west corner of T&CV, facing east down 10th street. Both shots are capturing the white truck as it is on 10th Street, about to enter the 10th & Morton intersection from the east.
That's an excellent point: the time stamp would have been off all night. Therefore, if any other vehicle had past those two cameras, during the time of interest, then those other vehicles would also have appeared to be "circling". Therefore, the white truck, since it was the only vehicle that was thought to be circling, we can reasonable conclude, was the only vehicle to drive between Morton Mansions and T&CV during the times the police would have looked at the footage for.
Another deduction occurs to me, regarding the bar-manager witness: she must not be on camera. Consider the interview Qualters gave, concerning the bar-manager witness (If you scroll down on the page, it's the interview labeled June 22nd, the third from last press conference):

Qualters seems to say, that the reason they don't believe the bar-manager witness on time is because of an
absence of video supporting her story. What he does not say is,
we have video of the witness coming and going, and it shows that she was in the area, but an hour off. I find this meaningful. If the bar-manager witness, for example, was "visiting a boy" who lived at Tenth & College (perfectly likely since she would have walked right past the south-east steps to see Lauren, had she been walking from the garage elevator to her car parked, say, on College Ave. out front), then that would prove that the camera coverage from whichever floor bar witness was coming from, all the way down the elevator, and out, was totally inoperable.
This raises the further possibility that the "employee" that the white truck was picking up lived at Tenth & College. (If the employee in fact lived at Tenth & College, then I'm thinking that the truck was headed north or west, since it continued west on 10th, instead of going east.) If the bar-manager witness saw Lauren and Mystery Man at 3:38, then that would give Mystery Man about 37 minutes to take Lauren upstairs, realize she's dead, and summon the white truck to come get her, at around 4:15. It's interesting, though it might be a coincidence, that 4:15 is also the time that JR's phone makes two calls.
