The footage published by ProPublica shows the last hours of Carlos Hernandez Vasquez, who was found dead May 20. He is one of at least six children to have died since December 2018 after being detained by border agents.
According to ProPublica, Hernandez staggered to the toilet in his cell in the middle of the night at the Border Patrol station in Weslaco, Texas, and collapsed nearby. He remained still for more than four hours until his cellmate awakened at 6:05 a.m. and discovered him on the floor.
