Paralleling a decade of growth, the U.S. Border Patrol has seen a rise in corruption and a troubling trend of the use of deadly force. Amid a national debate around police use of force, The Center for Investigative Reporting, in collaboration with Telemundo and MSNBC, spent seven months investigating deadly force by Border Patrol agents and how these incidents are handled by its parent agency, U.S. Customs and Border Protection.

Highlighting specific shootings involving agents and how a hiring surge that began more than a decade ago contributed to these issues, the investigation charted several incidents along the U.S.-Mexico border in Arizona and Texas.

Among those interviewed were victims, speaking publicly for the first time, of a brutal assault, rape and attempted murder by a Border Patrol agent in South Texas. Reporting from Washington, D.C., and West Virginia, correspondent José Díaz-Balart got an exclusive first look at a new Border Patrol training tool: a use-of-force simulator used to prepare agents to respond appropriately to threats. Along with interviews of former high-ranking officials, some speaking publicly about inside details for the first time, the investigation offered new insights into how the U.S. government has failed to hold the agency accountable.
