In 2010, The Guardian reported a rash of French women killing their infants and hiding the corpses in plastic bags in the garage, the garden, the trash. The foundation of the house. Usually more than one per woman.
One thing I would ask is what kind of bags. Why are the bags themselves reported. How small are the babies, is that the reason for “bags,” as in, small bags?
Are they zip-locking bags? Did they want to say that but the company asked them not to, because how awful, how awful? Let them please be opaque and brandless bags, they might have said.
I suspect a woman doing this over and over would at some point start using zip-locking bags. Everybody knows it doesn’t matter if you say it. You talk about bags this way and people are going to know you mean “zip-locking.”
