HOUSTON — In one photo, one of 88 men in a cell meant for 41 presses a piece of cardboard against the window, with the word “help.” In another, a man lowers his head and clasps his hands as if in prayer. And in a third, a woman wearing a surgical mask presses both of her hands against the glass.The images were released Tuesday by U.S. government auditors who visited facilities in South Texas where migrant adults and children who crossed the nearby border with Mexico are processed and detained.As public outrage grows over the conditions in which thousands of people — some no more than a few months old — are being held by the U.S. government, the report offered new cause for alarm. It quotes one senior government manager as calling the situation “a ticking time bomb.”“Specifically, when detainees observed us, they banged on the cell windows, shouted, pressed notes to the window with their time in custody, and gestured to evidence of their time in custody,” the report says. BuzzFeed first reported on a draft version of the report, which blurs most faces in the photos.An autopsy report also released Tuesday confirmed that a 2-year-old child who died in April had multiple intestinal and respiratory infectious diseases, including the flu. Wilmer Josué Ramírez Vásquez is one of five children to die after being detained by border agents since late last year.
