There isn't any new info to toss around right now, but there is one thing that keeps sticking out to me. Since I am not a local I may be off with this, but it really seems like the possible streets that MS took on her path home were all local streets. As in, would non locals have reason to be travelling on those streets at 2AM, none of them seem to be direct feeds towards the interstate. They seem like streets somebody would use to go home in the area, or be leaving a friends house from. IMO this has felt very local from the get go.
A side note that is noticeable in this case are the amount of RSO in the general area of her disappearance and LE not saying a word about checking them out (I know they are though). I can't remember the last young missing women where RSO's weren't thrown into the spotlight, at least for LE to say- yes were looking at them.
