Inside the Sentinel Surveillance Tower in Ciudad Juárez: A Podcast with Investigative Journalist José Olivares

Torre Centinela, a Mexican surveillance hub that will share intelligence with U.S. and Texas law enforcement is slated to open soon. Olivares discusses his investigation on Torre Centinela and the private corporation running it.

José Olivares is an independent investigative journalist and audio producer who reports on immigration enforcement, U.S. operations in Latin America, and human rights. He is also the podcast editor for The Border Chronicle, and we’re lucky to have him on our team.

In this episode, we discuss his recent investigation, “A Mexican Surveillance Giant You’ve Never Heard of Is Now Watching the U.S. Border,” conducted for the independent nonprofit outlets Rest of World and Type Investigations. José’s investigation focuses on the Torre Centinela, or Sentinel Tower, which is nearing completion in Ciudad Juárez, Chihuahua. This massive 20-story surveillance tower is truly dystopian and stands as the tallest structure in the region, overlooking both El Paso and Ciudad Juárez.

José toured the tower and examined thousands of government records related to Seguritech, the corporation overseeing the project. He found that surveillance in the borderlands is rapidly growing, often with little oversight, and that intelligence from the Sentinel Tower is being shared among Texas and U.S. federal law enforcement agencies. In Ciudad Juárez, which has faced violence for the past two decades, residents are voluntarily connecting their home security cameras to the Sentinel system with the promise of increased safety. But is it working? Listen to the podcast to find out!

Additionally, José explores the recent scandal involving two CIA agents who died during an anti-drug operation with state law enforcement in Chihuahua, which led to the resignation of the state’s attorney general.
