I'm seeing several posts mentioning how it must have taken 2 people to dig a shallow grave, trips to WM to buy shovels, etc.
For all we know, the "hole" she has been described being buried in, could have already been there and there was no need for a shovel at all. We also don't know if there might have been a shovel leaning against the house (I mean come on, everything else on the planet was thrown around the yard, why not a shovel too?) that whoever buried her, used. It's just weird that it was described as a hole though. Maybe that's just a regional thing, I'm not sure.
