I was looking at the case map and doing some google walks, and I am confused about where NH says he dropped her off. If it was right after you turn onto King's Creek Dr., it is about 600 feet to the first section of apartment buildings. When I pulled up a map of my house and measured out 600 feet from my driveway out it was about 2 blocks. That is not near as far as I thought it was. If it was the second set of buildings (up around the corner) that would be another 600-800 feet, still not terrible.
Then I started thinking about after she got out of the car. Did he do a 3 point turn right there and turn back on Ramsey? That road looks pretty narrow. If he drove down to the apartment entrance and turned around he would have passed her on the way out. Was she walking towards the apartments? Was she on her phone?
I know there was a video showing MB on the apartment patio. Can you tell from that which set of buildings it was?
ETA - I found an article that says the apartment was on Water Trail Dr, which is the first set of buildings. Not far at all to walk, however I still wouldn't want to do it in 46 degree temps in flip flops
