maybe someone she was with was doing the buying? maybe she was in the wrong place at the wrong time
She definitely was in the wrong place at the wrong time or this site wouldn't exist. Yet your point is plausible, she may have stumbled on something - the trouble with it is that she would have stumbled on it, on N. College just a short lit up walk from smallwood.
The stuff in the Alley has been inconsistently reported causing a lot of confusion. Police have never said that there is more than one video in the Alley. That assumption is coming as a result of the time discrepancy for the same video when it was first reported, and when Amin picked up the purse.
Until there is confirmation of a second video, the sequece is like this this:
2:40 CR gets punched at smallwood - LS is there.
2:45 CR/LS seen leaving smallwood on camera
3:00 Amin picks up LS's purse near Alley
3:15 to 3:30 Alley cam picks up CR/LS enroute to CR/MB's apt. where others are present (according to Salzman, CR's lawyer)
3:40ish MB says LS leaves and doesn't want to stay (I've not seen a statement where he says she wants to go off and party! )
?:?? LS gets together with JR who lives 2 doors down from CR/MB (we have no idea how this happened, could have been at CR/MB's, could have been elsewhere, there is no verification of how this happened by anyone or any camera)
4:15 to 4:30 JR says he sees LS leave (apparently from the 11th st. side of the building) and head down N. College toward Smallwood. A very short 3 minute walk in a well lit area with cameras on various buildings. She has no phone, no shoes, and lost her purse and keys back in the Alley which by now are up on the railing (not a rooftop!)
So the WRONG TIME appears to be between 3:45 and 4:30ish
... the WRONG PLACE appears to be Either
a) JR's place or where he took her in that sketchy 30 to 45 minute interval.
OR
b) Right there on N. College Ave about 2 blocks from her building on a well lit street, nearly directly across from a Waffle House frequented by local Police during that hour.
Another thought discounting random vehicle stranger abduction - How would a stranger in a vehicle know that she did not have a phone and could not call 911? If she felt unformfortable about a vehicle approaching her, she could have run screaming and this should have alerted JR (wherever he was standing when he lost saw her) if just a second later she screamed and ran, he should have turned or if he was on a balcony or near a window, poked his head back out. The timing would have had to be very precise, and the perp would have to know she had no phone... that confluence of events seems very against the odds
