I just cannot understand that if the parent(s) did kill Maddie then where was the body for the three weeks? And if it was hidden so well that it wasn't found why not leave it there instead of hiring a car and moving it?
That's a very good point.
I have my doubts about this DNA sample they alledgedly found in the hire car.
Was it really there, or have they simply shifted something from the villa they found into the car?
Would the Portugese plod really do that though?
I know we can't solve the case, but I find the mystery side of all this very intriguing.
