I'm still trying to get my head around all that's come out yesterday and today. But if something happened after EG got back from OG (or wherever she was), I would imagine that knowing what's happened is going to be a shock to someone. Surely it would take time to process it in your head, and then think what you're going to do about it?
I also feel if it was me that I'd not want to move a body outside the hours of around 1am to maybe 5am, because those would be the hours of least traffic and least chance of neighbors noticing me pulling out and pulling back in.
If I take the baby with me on the night time drive, if I get pulled over I can say the baby wouldn't sleep and I took her for a drive to settle her to sleep.
When I get to the spot where I'm going to dump, I don't think I want to be there long. I don't think I want to hang around to dig, and it's a dark moonless night so I can't really see to dig. If a cop comes along and I get caught carrying a shovel back to the car, that's going to be weird. If I get caught walking back to the car empty handed I can just say I pulled over for a call of nature in the bushes. If I back the car into an off-road spot, then I don't have to move the 'package' too far and I think I feel a bit more covered if only the front of the vehicle might be visible from the road and the vehicle itself might become part of my cover along with some trees or bushes that I park behind? Maybe I leave the lid of the trunk up and feel a bit more comfortable this way walking a few yards with a flashlight, or maybe one of those headband lights if I have one so that I can keep two hands free.
