On May 23, 2018, at approximately 12:22 p.m., a lone Border Patrol Agent responded to a report of illegal activity near a culvert by Centeno Lane in Rio Bravo, Texas where he discovered a group of illegal aliens.
Initial reports indicate that as the agent attempted to apprehend the group, he came under attack by multiple subjects using blunt objects. The agent fired at least one round from his service issued firearm, fatally wounding one of the assailants. The rest of the group fled the scene. Border Patrol Agents called for EMS and administered first aid until the Rio Bravo Fire Department arrived.
Three illegal aliens related to the incident were subsequently apprehended by responding agents.
The incident is currently under investigation by the Federal Bureau of Investigation and Texas Rangers.
