Kate (R) and Gerry McCann, the parents of missing Madeleine McCann, join the families of other missing children to highlight International Missing Children's Day in central London on May 18, 2009. The police officer who formerly led the Portuguese investigation into the disappearance of British girl Madeleine McCann said he would counter sue the missing girl's parents Sunday. "My lawyers are working on the case and we will take the McCann couple to court and perhaps other people for defamation, slanderous denunciations and false statements," said Goncalo Amaral on Portuguese TVI television.
