Here is part of an interview with Amaral which is full of his crappy speculations
Q - What is your opinion?
A - To me, Gerry hid Madeleine's body on the beach. And after a few days he moved her with his car. We work following this lead. Trying to find out the date of the switch, some details, but we were on the way. The Irish [witness] was about to arrive in Portugal, but everything was delayed too much, he even received external pressures. In the end, he didn't testify for the Police.
Q – They [McCanns] have appeared in all the media to announce the disappearance of their daughter and if it ends up that they have done it, what are they, psychopaths?
A – No, they are human. If the McCanns admit that their daughter is dead, they can no longer collect money from the Maddie fund, and that's a lot of money, over one million pounds. That's why they say that the girl was abducted.
Q - What if they do not want to lose hope? It all seems very morbid.
A - It is. If they admit that she is dead they will lose their style of life. They are human, not psychopaths.
Q - You said that the girl was frozen.
A - For there to be vestiges in the boot of the car rented 23 days later, they must have preserved the corpse in some way. I believe that when they put it in the boot, with the heat of those days in the Algarve, a similar situation happened with that of shopping bags, which melt, and then the water is transferred to the car.
