Kate McCann muttered it under her breath, she did not say it to the detective.

"Each time a dog gave a signal, Ricardo would pause the video and inform me that blood had been found in this site and that the DNA from the sample matched Madeleine’s. He would stare at me intently and ask me to explain this.These were the only times I didn’t respond with a ‘No comment.’
Instead I said I couldn’t explain it, but neither could he. I remember feeling such disdain for Ricardo at this point. What was he doing? I thought. Just following orders? Under my breath, I found myself whispering,‘F*****g t****r, f*****g t****r.’ This quiet chant somehow kept me strong, kept me in control. This man did not deserve my respect. ‘F*****g t****r . . .’"
