A fourteen-year-old Mexican boy is being buried today, less than forty-eight hours after being shot by a US Border Patrol agent on Mexican soil. Mexican officials say Sergio Adrian Hernandez Güereca was shot in the head. Graphic photos published in the Mexico press show the boy lying next to a pool of blood. Sergio and his friends were reportedly playing in a dry section of the Rio Grande and throwing rocks at border guards. The Mexican government has condemned the shooting, saying the use of firearms to respond to boys throwing rocks was a “disproportionate use of force.” An eyewitness said Hernandez was clearly on the Mexican side of the border when he was shot.

Eyewitness: “Once the youngsters were on Mexican soil, an official — I don’t know if he was an immigration agent or a police officer — arrived on a bike, wearing a white shirt, a helmet and shorts, and he shot at the youngsters, at the whole group. Some ran in one direction, and others in another. This one teenage victim hid behind the wall. He looked out, and that’s when the teenager was shot.”

The shooting comes just weeks after President Obama announced a plan to send an extra $500 million and 1,200 National Guard troops to the border. Two weeks ago, a Border Patrol officer in California shot and killed an undocumented Mexican immigrant with a stun gun. The thirty-two-year-old Anastacio Hernandez had lived in San Diego since he was fourteen and had five American-born children. Border Patrol agents claim he had resisted being deported.
