My bestie told me that the tank's manhole is attached to the surface. A quick mechanical procedure to unscrew the lid and then lift up. Once you are finished, proceeds to flip down and reattached. Tanks could have different sizes and openings; circumferentially speaking.
Which leads me to the mechanical/manual labor of what ensue at the oil field.
Park the pick up, open door, grab body, up the ladder, proceed to place the body on the floor, unscrew manhole lid, lift lid, pick up body, dump on the tank, close lid, grab the wrench/tool, reattached. Go down to the stairs and repeat process.
Dig a shallow grave (read Bill Carson's post about digging a grave); go to the pickup, pick up the body of your wife who is carrying a baby inside, dump her on the ground, shovel dirt available from a recent excavation and covered her body. Back to pickup .. and back to business as usual.
My stomach is turning as I'm writing this. To the people who don't agree with my accomplice scenario, maybe you are right, maybe not. Maybe my mind can't process how can someone did that twice and them dig a shallow grave (read Bill Carson's post about digging a grave);. That's why I speculate of an accomplice; because I can't fathom what I described above.
Uncanny, disgusting, eerie, cruel, selfish, evil, vicious and unnecessary.
