On 31 August 2007, the parents of Madeleine McCann announced that they were suing the newspaper for libel after the newspaper reported that the "police believe" Kate and Gerry McCann killed Madeleine, suggesting she may have died in an accident or from a drugs overdose. The police stressed that the McCanns were not suspects (at the time: they later became so), but "Tal &amp; Qual" stood by the story. The journalist who wrote the article, Catarina Vaz Guerreiro, said "I can't reveal my source, but I have complete trust in them. I strongly believe that the person that gave us this information is telling the truth."
