I have just been reading the statements of SILVIA MARIA CORREIO ROMOS BATISTA, the person who helped to translate questions to the Police on the 3rd of May. The person that posters say didn't mention that Kate asked for the twins to be tested for drugs.
Well, she doesn't exactly say what she translated, she just said she helped to translate, there is nothing about how Kate found the children etc.
What I did find though that she made a lot of negative remarks, she thought it strange that the window that the McCann's said was open was far from the bed of Madeleine and there wasn't enough room for someone to have taken Madeleine from her bed and out through the window. That the group and the parents weren't bothered about searching. That Gerry got down like a praying arab when the Police arrived. That she found it strange that someone could have seen another person crossing the road from the angle they were standing.
Another thing I noticed was the mistakes she made, she said the witness to the man crossing the road with a child was 'dark skinned', and that the parents took the twins from their cots to the other apartment.
Sorry, but I wouldn't call her a reliable person to say whether or not Kate asked for the twins to be tested for drugs.
