Allison Wyatt, Sandy Hook child victim turned up to have a fake (wrong) photo, as published in the UK Daily Mail and elsewhere. The photo was taken from another family's open, public Flickr album and the family name is not similar at all.

The victim name and ANY photo are missing from the tribute video:

If this is a pre-set operation where nobody was supposed to die (or very few), this would make sense ... while the Wyatt photo was in dispute, put up no photo on the tribute video, so as to call less attention to her, for those who can be counted as uninformed public.
