From where do you get this info? Pre-funeral visitations used to take place in the house of the person deceased, now they take place in the funeral homes. The casket is taken out from the funeral home and brought to the church in the day of the funeral.
Interesting statement.
"The casket is taken out from the funeral home and brought to the church in the day of the funeral."
So when was it exactly that Madeleine's parents managed to retrieve her body from where ever, smuggle her into the church, unscrew the coffin lid, place madeleine inside, screw the lid back down and make their exit without anyone noticing? Job done.
On the day of the funeral as you claim, there was absolutely no chance of that.
As there was absolutely no chance that the smell of death emanating from a month old corpse would not have required an Eddie to notice it.
If the coffin had lain in the church over night ... in a town crawling with media and journalists who no doubt knew the parents visited the church ... how could it have been accomplished? Bearing in mind that the smell would be even more overpowering.
More interesting ... why is it only now that Dr Amaral is suggesting this as a theory? is it because the lines the new investigations are following quite obviously owe nothing to his original theory, so he felt the need to invent a new one?
