Carlos Gregorio Hernandez Vasquez, a 16-year-old Guatemalan migrant, was seriously ill when immigration agents put him in a small South Texas holding cell with another sick boy on the afternoon of May 19. A few hours earlier, a nurse practitioner at the Border Patrol’s dangerously overcrowded processing center in McAllen had diagnosed him with the flu and measured his fever at 103 degrees. She said that he should be checked again in two hours and taken to the emergency room if his condition worsened. None of that happened. Worried that Carlos might infect other migrants in the teeming McAllen facility, officials moved him to a cell for quarantine at a Border Patrol station in nearby Weslaco. By the next morning, he was dead. In a press release that day, Customs and Border Protection’s acting commissioner at the time, John Sanders, called Carlos’ death a “tragic loss.” The agency said that an agent had found Carlos “unresponsive” after checking in on him. Sanders said the Border Patrol was “committed to the health, safety and humane treatment of those in our custody.” Related This Is What a White Nationalist Administration Looks Like Smugglers Use Household Tool to Easily Penetrate Trump’s ‘Virtually Impenetrable’…
