Britons Kate McCann (C) and her husband Gerry McCann (L), parents of missing British girl Madeleine McCann, arrive to the court house in Lisbon on June 16, 2014 for the closing arguments of the McCann couple's libel proceedings against former inspector Goncalo Amaral for a book written about the case of their missing daughter. Kate McCann and her husband Gerry are suing Amaral in a Lisbon court for the book in which he argues Madeleine was killed accidentally and implicates her parents in her alleged 2007 death.
