Trying to think through the mechanics of how this altercation involving CR /ZO actually occurred.
My assumption here is based on the timeline of CR/LS being on video as entering Smallwood at 2:30AM and being on video as exiting Smallwood at 2:42 AM as is posted on this site's maps per page 1 of each thread. It also assumes what I believe to be reported that the confrontation happened on/at/near the Smallwood 5th floor elevator lobby.
--Assuming it took CR/LS 2-3 minutes from entering front door, walking to elevator to hit button, perhaps waiting for elevator, rising 5 floors, . . . . plus another 2-3 minutes of same actions upon return, that only leaves perhaps 6-7 minutes for actual altercation.
--Was ZO/friends already waiting at 5th floor lobby for CR/LS to get off the elevator? If so, how did ZO/friends know CR/LS were coming back there and soon enough to beat them to that spot . . . .unless ZO/friends were already at apartment (with HT as a wild guess??) LE must have Smallwood video of when ZO/friends entered Smallwood themselves and what points they were on camera throughout the building at various times.
--How did ZO/friends actually get up to the 5th floor? It's been posted that a resident card code was needed to activate the elevator upward. Was someone in ZO's party a Smallwood resident? IF ZO's party somehow knew CR/LS was coming to Smallwood, they could've had this quick altercation in the main floor lobby and made a much easier/faster "getaway" than on 5th floor. And why exactly did the altercation occur here inside at Smallwood in the first place and not outside? Would they not have preferred this "fight" to occur in the dark/outside as opposed to light/inside, & where no cameras were? Unless the altercation wasn't exactly pre-meditated but more stumbled upon via 5th floor elevator encounter.
--Has LS's apartment been confirmed to be on the 5th floor? Which floor did DR live on? IF both lived on the 5th floor, could it be assumed that CR/LS were returning to her apartment and not DR's? Would LS's apartment have been empty at 2:35? (where was HT at this time?) Was DR's apartment occupied only by DR at that 2:35-ish time?
--How and when did ZO's party exit Smallwood? Presumedly they didn't all share an elevator down with CR/LS. If CR/LS went down the elevator first and headed out the door, it would again have required ZO's party to have known where CR/LS were headed, and passed them or beat them to the spot via an alternate route (on cameras?) to have possibly met them again near the alley/gravel lot less than 10 minutes later if indeed that happened. If ZO's party went down the elevator first and left the building first, they could only have known where CR/LS were going if they lurked outside Smallwood and followed them to alley/gravel lot. Again LE should have Smallwood video confirming the correct sequence.
--Did no other resident on the 5th floor hear anything, or peek their head out of their door, or call for security at this hour? Surely someone was aroused from sleeping or already awake and heard raised voices, punch(es) thrown, bodies scuffling, etc. Even in this environment of a college town, this type of event at 2:35 AM would surely have to be unusual.
I will say I have to keep reminding myself that all of these events occurred so late in the evening (entirely in the morning actually) and all while dark, and all so compressed together in terms of time. For some reason I keep picturing the evening beginning while still dusk, and events happening over a much wider timeframe which tends to give a different perspective.
