This case you keep quoting - I've looked it up. I think they the circumstances are barely comparable. For a start the police have literally no idea who dunnit. Therefore that person who did it may have planned the murder well in advance, procuring a freezer quite comfortably in advance of the murder and installed in the privacy of their own home for just that purpose. This is at odds with Amaral's theory that MAdeleine died accidentally whilst on holiday and was put into a freezer for 23 days. What freezer? Where? How did holiday makers avail themselves of a secret freezer for that length of time?
I was a bit closer than just looking it up.
The reason I bring it up is that the body was stored in a freezer or maybe a Letchworth Bacon Factory refrigerated truck. Which rather shows up those who have consistently ridiculed the idea of bodies put in freezers.
Of course bodies of little girls aged nearly 4 carrying tennis balls in a case where the SIO is a Portuguese with initials GA. That might be different.
However the principle of bodies in freezers and "doing simple tasks in faraway places" are well established.
