EXCLUSIVE: Los Zetas Cartel Leaves Message for U.S. Agents in Texas

Border Patrol Agents, while responding to a large drug load crossing into the U.S., discovered a message from Los Zetas Cartel over the past weekend.

Rio Grande City, Texas, is a small community in Starr County situated on the border with Mexico. The area is documented as being under the control of the Gulf Cartel, due to the small cartel-controlled community of Camargo directly across the Rio Grande.
