I guess I don't WANT to believe it's the parents. Although I must admit I think the way they've handled the whole thing quite weird. How stoic they've been.
Mind you, that doesn't mean they did it! What about that girl whose fiance was murdered in the bush in Oz? One of the reasons everyone thought she did it was because she seemed so collected on TV. I think she had a breakdown later though and she was proven innocent and they caught the real murderer in the end.
As for the blood in the car, perhaps that's the car the murderer used and it went back in for rental and then they rented it - just an amazing coincidence?
It's all so intriguing. And very very sad.
If they ARE found guilty I'll also be so fucking angry at how they've manipulated people's good nature. It will make everyone more jaded about situations like this and less inclined to help the next time a child really IS abducted.....
