I also think the timeline would be tight, as AA said her encounter was around 6:00 p.m.. The only other odd occurrence I remember seeing was rumor of someone claiming that DS pulled into a gated apartment complex just prior to reaching her own. Again, it is rumor. But if it checked out with LE, maybe the initial plan was for the SG to go back to DS's apartment and leave her vehicle there immediately upon leaving ML and planned to have a friend meet him there. If DS was scared or trying to alert someone by pulling into another location, it could have derailed the SG's attempt to take DS quietly from her complex and he could've forced her to drive directly to his home instead. I'm not saying this possibility has much weight, just throwing it out as a scenario to tie in with AA's reported encounter. All MOO.
I have a thought that whomever Atomic Angela saw the day Dani disappeared may actually have been involved. Between the police contacting her about it again, and her absence since the thread was down makes me think she might not be able to talk about any of it anymore, at least I hope that's the reason she isn't on here. The thing I can't quite figure out is exactly how he may have been involved, especially since it was so close to the time of her disappearance.
