Apparently, Shani Louk, the girl that was at the festival and in the truck video and was eventually confirmed alive and being treated in Gaza, is dead.
I've found very little reliable information on it but it seems the Israeli foreign ministry contacted her mother to tell her they found a DNA-checked "skull fragment" suggesting she was dead since October 7th.
I have literally zero proof of this but I genuinely consider it likely the IDF killed her (most likely through bombings), found her subsequently, and are now lying as usual.
Unless there's a huge secret instance somewhere that isn't federated with any other of the large instances (there isn't):
