Watching Larry King interview regarding the Madeline McCann disappearance.
75% of child murders are resulting from the parents hitting the child too hard and then trying to hide the body. Maybe I have made a mistake on the finer details, but it was close. Nevertheless, it is a high percentage and it is shocking.
Also, the parents McCann are both doctors. If they hit too hard, they would certainly know what harm it could cause.
This talking head doctor also mentioned that if the body of Madeline was deposited at see, it would be "skeletonized" so much that any cause of death would be very difficult to establish if the body were found.
(I am embarrassed by being stuck into a gossipy-news, but I was travelling and it kept reappearing in office reception televisions).
