I forgot to mention, I did see a camera in the loading dock, which is visible in one of the google map images above. It is white and circular, above the stack of blue crates. After viewing the whole back of the store in those images, there are multiple cameras visible. There is a camera above the door next to the fenced in green box, to the right of where they supposedly parked. So how did this camera not show the murders? Was it too dark to show anything? Was the camera pointed at the wrong angle? Was it not turned on? Was Natalie's SUV blocking the movement? Very strange.
There are multiple electrical boxes back there. He could have hid behind any of them, or more than one, as he was stalking them. The one that is fenced in definitely looks climbable. Maybe that's what he climbed "like Spiderman." If he was afraid he would be seen by the victims, he could have climbed up the structures next to the loading dock. There is an electrical box in the grass too.
I agree the delivery truck must have been coming from behind King Road. Now I'm not sure which way the victims came in. Since there are cameras all along the back, any of them could have caught their picture. I think Jeff walked around the Publix building close to the Highway 92 side, because it would have been a shorter walk, and there were more places for him to climb and hide behind.
There's also a Waffle House down Crabapple Road, close to Natalie's house, but that doesn't seem like an area Jeff would have been in because of his route that night, so that's why I was guessing it was the Waffle House on 92. Just throwing it all out there.
Drove by last night. It's well-lit at night. I'm thinking that one camera above the door doesn't reach that far or the cars were blocking the view.
