Arizona:"Most sophisticated narco tunnel ever discovered" stuns authorities video

Chivis Martinez  ICE Press Release

Special agents with U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) discovered an unfinished cross-border tunnel Tuesday after several days excavating the sandy Sonoran desert terrain outside of Yuma, Arizona. The discovery is a result of an ongoing HSI-led multi-agency investigation.

The U.S. portion of the tunnel reaches from the 1300 block of Los Olivos neighborhood in San Luis, Arizona, stretching past the Mexican border and under the fence extending more than 1,300 feet to Calle 10 and Ave. Capitan Carlos G. Calles in San Luis, Mexico. Preliminary photographs reveal the man-passable passageway measures 3 feet wide and 4 feet high and is equipped with a fully developed ventilation system, water lines, electrical wiring, rail system, extensive reinforcement and shoring, known to be commonly used in sophisticated subterranean tunnels. The tunnel was detected prior to completion, and there was no access from the tunnel to the surface in the U.S.

 “Homeland Security Investigations and our esteemed law enforcement partners swiftly and effectively worked together to uncover and dismantle a cross-border tunnel for smuggling purposes into the United States,” said Scott Brown, special agent in charge of HSI Phoenix. “Despite the international pandemic, HSI and our law enforcement colleagues remain resilient and committed to pursue dangerous criminal trans-border smuggling activities along the southwest border.”
In mid-July, federal agents discovered a sinkhole along the U.S./Mexico border between the primary and secondary border fences. HSI special agents responded to the area and observed the sinkhole was in line with the area of an ongoing tunnel investigation. With the assistance of federal partners, on July 27, Yuma Sector Border Patrol commenced drilling near the sinkhole site; shortly thereafter, pieces of wood and water hoses were discovered underground, as well as a void. A specialized camera was deployed 25 feet underground to investigate the gap revealing the cross-border tunnel.
 “This appears to be the most sophisticated tunnel in U.S. history, and certainly the most sophisticated I’ve seen in my career,” said Carl E Landrum, acting chief patrol agent, Yuma Sector. “We will continue to work closely with our partners – Homeland Security Investigations and state and local agencies to provide the best national security possible.”

This is an ongoing HSI-led investigation with assistance from Yuma Sector Border Patrol, HSI/Border Patrol San Diego Tunnel Task Force, U.S. Customs and Border Protection’s Office of Field Operations, the Drug Enforcement Administration Yuma Resident Office, the San Luis Police Department (Arizona), and the Yuma County Sheriff’s Office. The U.S. Attorney’s Office for the District of Arizona is also supporting this investigation.


  1. I thought the "guardian" was gonna give us a tour to see it, just like "chapo"´s escape tunnel from CDMX

  2. tunnel in dirt, But sand that must be really challenging. They had a professional architect that was good but not that good. Imagine in a sand timer all that sand washes down from that tiny hole. In this case thats exactly what happen.

    1. The thing is, these things are not meant to last years

  3. That was a very difficult tunnel to construct.
    Tunneling through that kind of soil is extremely difficult and next to impossible for anyone without a sophisticated operation.
    My assumption is that the cartel (which one, I have no-idea) selected that location just because it was so unsuitable for any kind of a tunnel.
    Based on that they assumed that the Americans wouldn’t be seismically monitoring the area, when in reality we seismically monitor as much as we can and sometimes we have sophisticated means of detection that aren’t commonly known.
    Also, that type of soil is a very difficult to detect much because it’s such a poor transmitter of vibration or infrasonic sound waves.
    No, that tunnel was detected by non-traditional means, be it informers or airborne mean the cartels don’t know about.
    A win for the good guys this time.

  4. Architect=fired

  5. sand no bueno. one can imagine the effort involved. think lots of water alot alot alots
    lots of water to dampen those inner walls as its construction progresses. traditional bracing with just wooden beams wont cut it... they probably sprayed plaster type material to hold some shape and then reinforced with determination and creativity. suprised there hasnt been a tunnel constructed in sections using those kids playhouse tunnel slides found at fast food joints in usa...

    imagine it with me for lulz..

  6. What Did You Just Day 🔝?
