Combine the shoes with the fact they report the ages as 9,9,9, for the children, and 61,60,61 for the adults and the address of 33 and 3 adults and 3 kids, again 33, the school employs 33 teachers...... 33 for masons. This doesn't have to be accurate, but the fact they put it in the media with those numbers means it's their indicator to each other not in the loop that this was a staged event.
