If entry was through the property’s back door, most of the time spent inside, including the subduing of NG, happened well before the video footage.
Remove camera around 2:12 am, leave straight afterwards with NG, with blood spatter on the porch tiles showing the route out. That’s the sequence I’ve assumed ever since Levin said FBI agents told him the video footage was from 2:12 am. The moon shadow analyses posted here previously seem to back that up.
One question, though probably not an important one.
The perp could clearly open the front door from the inside in order to leave with NG, creating the droplets in the process. So if he was inside already and could open that door, why walk around the outside of the house again to remove the camera? The same thing applies if the person we see was part of a team. They were already inside, and later left through the front door. Why walk around the house?
Why didn’t he open the front door to remove the camera, which was mounted right next to the entrance?
He could even have used something from the house to help force the camera from its mount. He would mostly have avoided being on camera, though not entirely. (We’d have seen his gloved hand and his arm – the camera’s angle of view was so wide that we see the front door handle in the lower right of the footage.)
The likely walk around the house and the use of the lantana are probably indicators of something. I just don’t know what.
Did he worry that there was an alarm or sensor on that door, and want to delay opening it for as long as possible? Did he need to get something from his vehicle before removing the camera? Did he worry that the camera would record audio of NG if the front door were open? Were lights on inside, which would have switched the camera away from night mode when the door was opened?
