Heard about this one from a church deacon. It's been a few years, but this is generally how the story went:
A couple who were not regular church attenders dropped off their kids at the church nursery, then left. Eventually, church ended there was no one was there to pick up the kids, and the parents weren't answering their cell phones. The people working in the nursery got the head deacon involved, and when an hour had passed after church and still no one had picked up the children or had called or had answered the cell phones, the children were turned over to our local Child Protective Agency. There were two children, and if I remember correctly the older of the two was about 18 months old and the younger was an infant.
He told us that the parents were eventually tracked down and arrested.
There were some changes made to how and when kids could be dropped off at the church nursery. Specifically, there would be no dropping kids off at the nursery then leaving.
