3 or 4 Year Old Boy Left in Baby Hatch

I posted a story about Japans first Baby Hatch opening last week at a Kumamoto hospital. On the first day the hospital was very surprised to find a 3 or 4 year old boy placed in the hatch. The hatch is meant to be a safe haven for babies of parents that are unable or unwilling to take care of them. No one was expecting a 3 or 4 year old child to be left there. Police are investigating whether this is a case of neglect and abandonment.
