Living in a house in a rural area, I used to leave my babies sleeping in the car when I unloaded groceries. We rarely lock our cars in the driveway. My suburban/urban friends would never think of doing that. They lock the car doors and bring the keys with them between trips into the house when unloading groceries. However you do it becomes a habit, part of your routine.
Do we know if Blaise’s parents recently moved from a rural area? Or have they lived in that area for a while? Would leaving the car doors unlocked and the keys in the car be part of their normal routine? (Rhetorical questions)
When first reported the story was believable and I expected Blaise and the car to be found together within a few hours. The car being found but no sign of the baby, brings up all kinds of questions. The first one I have is: When was the last time anyone outside the family saw the baby? Was he even in the car?
