> I think MM's parents know what happened to her. All these years on and listening to what criminal profilers have to say about the case, that's my conclusion
Police have drug dogs that indicate when they are in the presence of drugs.
Cells release a certain chemical after death.
Police also have indicator dogs which indicate when they are in the presence of the chemical dead people release. Not just decomposing bodies, but even very freshly dead people.
I can't remember the name but I watched a documentary which said that in Madeleine's room it indicated in the wardrobe and also in the boot of their rental car. Of course that can't be used as evidence as hundreds of other people had used the car and hotel room.
There's a theory that the children were routinely sedated so that they would not wake up when the parents were out. Not necessarily with a prescription level drug. Even over the counter antihistamines are routinely (controversially) used by parents for this purpose. Overdose/bad reaction and the child unfortunately passes away.
The child is already deceased and if that was found during an autopsy both would probably lose their medical license and face even heavier social criticism for leaving the children alone.
It was suggested that the body had been disposed of in the sea, meaning it is unlikely to be found.
Yes, there were some known pedophiles in the vicinity, but if you look at the 3 Australian children who disappeared, there were like 6 pedophiles in the vicinity, some of them involved in other disappearances. It's not rare for there to have been a pedophile in the vicinity.
