Once you smell it - you'll know and you'll never forget...
Try to imagine the stench from 80 or 90 corpses, 60/200 meters to your front, after a few very hot and humid days.......
As soon as it's safe to do so -- nothing receives higher priority than getting them dragged away or covered with enough dirt/mud to stifle the stench....
...”Once you smell it - you’ll know and you’ll never forget..”
I’d imagine so....which begs the question...why was the grandmother familiar with what a dead body smells like? Any possibility that she’s involved?
