Gustavo Santiago, a 13-year-old from Tamaulipas, Mexico, living in San Antonio, Texas, was detained with his mother on October 5, 2025, at a Border Patrol checkpoint. He has been sick multiple times in detention. When he had a fever, medical staff told his mother he was old enough to fight it off without medication. He was treated for a skin rash believed caused by poor water quality and suffered stomach pain and nausea attributed to unsanitary food preparation. He expressed fear of deportation and uncertainty about what he did wrong to be detained.
