There are a few things I'd like to add to this case. (First post, been a voyeur the entire time)
First is this IMGUR post to share:

Second is the time between 4:30-5pm on 12/2, may have looked nearly identical to the daylight as 12/9. I took a photograph (No HDR or special effects/filters-Also, to head the comments about photographing/driving off, we were nearly stop and go the entire time) at 4:51PM, around the Southfield Rd/ M14 exchange on the 9th. Only to really provide a bit more evidence that it was still daytime and night hadn't set in yet. It's overcast, but it should represent the amount of light during these hours. A daytime abduction is risky, especially near the time people would be leaving work and/or coming home. IMO, I would see something happening inside the apt hallway/doors vs outside. Unless these are brazen criminals(or stupid), doing it in daylight is harder to get away with.
Third - Recent attempts or other missing persons cases:

http://www.candgnews.com/news/police-search-missing-southfield-man-98010/ - Though really the first one. That was a daylight attempt, around 4:30PM.
If I think of anything more I will post it.
