An earthquake in 1972 destroyed nearly 90% of Managua, resulting in massive destruction to the city's infrastructure. Instead of helping to rebuild Managua, Somoza siphoned off relief money. The mishandling of relief money also prompted Pittsburgh Pirates star Roberto Clemente to personally fly to Managua on December 31, 1972, but he died "en route" in an airplane accident. Even the economic elite were reluctant to support Somoza, as he had acquired monopolies in industries that were key to rebuilding the nation.
