Officials have said Carlos was detained without his parents near Hidalgo, Texas, on May 13 and held in the McAllen processing center until last Sunday. That morning, Carlos told agents he was not feeling well and a nurse diagnosed him with the flu. He was treated with Tamiflu and moved to a Border Patrol station about 20 miles away in Weslaco, where he could be isolated from other migrants. The next morning, he was found dead during a routine welfare check.
