The only way the police will ever find Maddie is if her parents tell them. At first I believed their story but after all what has been brought to our attention recently I am being to think that they accidently killed her by sedatives and got rid of her body. You see Maddie had trouble sleeping, and police have repeatedly asked the McCanns if they overdosed Maddie.
Evidence found in the boot of the hire car suggested this, as a large amount of hair and bodily fluid was found not something that could be transfered by another item ie clothing or a blanket – police think it came form Madeleine herself. The only reason that the McCanns have probably not been charged is because untill the child is found – there is no substantial evidence to convict them.
