This was my thought too... sometime in the near future we'll see a news article with a title like "Children abducted, mother heartbroken" and then some time down the road after the police expend countless resources trying to find them we'll find out it was the mother all along. That she drove her car into a lake with them strapped in the back seat or some shit. A similar situation happened a couple decades ago in the US somewhere. I recall reading about it.
