A federal judge has dismissed a lawsuit filed against the nation of Cuba by a Maine woman who claims Cuban officials caused the death of her father in 1963. The judge dismissed the case Wednesday because Cuba has failed to respond to repeated summonses. Sherry Sullivan of Stockton Springs sued this year, after winning a state court ruling in 2009 that Cuba was guilty of the wrongful death of Geoffrey Sullivan, a pilot believed to have been shot down while on a covert mission. The state judge awarded Sullivan a $21 million default judgment. Sullivan’s filing in federal court in Bangor sought to enforce the judgment. The Portland Press Herald reports that the judge dismissed the case after receiving no response from Cuba to three orders.
