After Hurricane Maria devastated Puerto Rico, Efrain Perez felt a pain in his chest. Doctors near his small town sent him to Puerto Rico's main hospital. But when the ambulance pulled into the parking lot in the capital, San Juan ... a doctor ran out to stop it. He said, 'Don't bring him in here, I can't care for him,'" Perez's daughter, Nerybelle, recalled. Perez died as the ambulance drove him back ... but he is not included in the island's official hurricane death toll of 64 people, a figure at the center of a growing legal and political fight over the response to the Category 4 storm that hit Puerto Rico on Sept. 20, 2017. Facing at least three lawsuits demanding more data on the death toll, Puerto Rico's government released new information on Tuesday that added detail to the growing consensus that hundreds or even thousands of people died as an indirect result of the storm. According to the new data, there were 1,427 more deaths from September to December 2017 than the average for the same time period over the previous four years. The Puerto Rican government says it believes more than 64 people died as a result of the storm but it will not raise its official toll until George Washington University completes a study of the data being carried out on behalf of the U.S. territory. Like Perez, thousands of sick Puerto Ricans were unable to receive medical care in the months after the storm caused the worst blackout in U.S. history, which continues to this day, with 6,983 home and businesses still without power.
