Unbelievable...I didn't read the comments yet my words were near identical about balancing on a toilet. As are many across the Internet. The footprint probably was on the toilet seat due to the child trying to get footing so he could live.
Salem, there was also an incident like this in Canada, 1998 think it was. I only found the lead-in to the story but in that it said other kids were involved. Weird things do happen but 'accidentally' hooking the back of ones shirt collar on a hook high enough to hang from?? Like you, would like to hear what that child has to say. If he is able to say.
