Look at the kid in post 22 and post 25. It looks like they could be twins. Even the sandals look the same. Further, the kid in the coffin is wearing clean street clothes. Only martyrs are buried in the clothes they died in and if the consider him a martyr, he would still be further wrapped in a white cloth.
I”n preparation for burial, the family or other members of the community will wash and shroud the body. (If the deceased was killed as a martyr, this step is not performed; martyrs are buried in the clothes they died in.) The deceased will be washed respectfully, with clean and scented water, in a manner similar to how Muslims make ablutions for prayer. The body will then be wrapped in sheets of clean, white cloth (called the kafan).”
The one in #22 has no blood or evidence of external wounds anywhere. The sandals are similar but don't seem to be the same color. The ones in #25 are bright, clean, new - even the soles are clean.
Is that blood on the fingertips of the hand holding the coffin lid?? Or just discoloration of some kind? There is blood on the child, but it seems to have been covered by the clothes, although the clothes don't seem to have blood soaked into them from the wounds. Interesting, no?
Do they actually just unceremoniously dump a child's body into a wooden casket and tack the lid on? No padding, no covering, no wraps? Just let the child rattle around in a big, ol' empty wooden box?
According to your descriptions, I would expect this child's body would be handled differently than just being dumped into an adult sized casket, still bloody but with new clean clothes and sandals on.
All I'm sayin' is that none of this passes the smell test for me.
