Sergio Hernandez died in Mexico, but the bullet that killed him was fired from the United States. The 15-year-old boy was shot in the head by a Border Patrol agent in 2010. The agent, Jesus Mesa, initially said Hernandez was throwing rocks in order to distract agents from a smuggling operation; his parents say he was simply playing with friends along the unmarked border that separates El Paso, Texas, from Juarez, Mexico.
The Hernandez family sued, alleging that Mesa violated the Constitution when he killed their son, but an en banc Fifth Circuit tossed the suit. Now, the Supreme Court will take up Hernandez's case, ruling later this term on how far constitutional protections against excessive force can reach.
