It's hard to say for sure. The author might have drawn inspiration from real-life experiences but could have embellished or changed details to make the story more engaging.
We can't be certain based solely on the title. It could be that the so - called 'baby snatching' is something that has been misconstrued. There could be a back - story where the friend was wrongly accused, perhaps due to being in the wrong place at the wrong time or some miscommunication that made it seem like they were involved in baby - snatching when in fact they were not.
