PHOENIX, Ariz. – During the week of enforcement operations from July 19, 2025, through July 25, 2025, the U.S. Attorney’s Office for the District of Arizona brought immigration-related criminal charges against 135 individuals. Specifically, the United States filed 67 cases in which aliens illegally re-entered the United States, and the United States also charged 50 aliens for illegally entering the United States. In its ongoing effort to deter unlawful immigration, the United States filed 11 cases against 13 individuals responsible for smuggling illegal aliens into and within the District of Arizona. Protecting law enforcement is a key part of border vigilance, and prosecutors also charged 5 individuals in 3 cases for assaulting federal officers.
These cases were referred or supported by federal law enforcement partners, including Immigration and Customs Enforcement’s Enforcement and Removal Operations (ICE ERO), ICE Homeland Security Investigations (HSI), U.S. Border Patrol, the Drug Enforcement Administration (DEA), the Federal Bureau of Investigation (FBI), the U.S. Marshals Service (USMS), and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
Recent matters of interest include:
United States v. Santos Mendivil Contreras, Jr., et al: On July 22, Santos Mendivil Contreras, Jr. and Emanuel Mendivil Cervantes were charged by criminal complaint with assaulting federal officers. Homeland Security Investigations (HSI) had been investigating Contreras based on his unlawful presence in the United States and his attempt to purchase firearms in April 2025. After multiple unsuccessful attempts to contact Contreras in June and July, HSI agents initiated a traffic stop on July 22. Contreras, who was accompanied by Cervantes, attempted to flee by accelerating the vehicle. He ultimately stopped in front of his residence, exited the vehicle, and began walking toward the home. An HSI agent drew his firearm and gave commands, at which point Contreras reached for the agent’s weapon, leading to a physical struggle over control of the firearm. Three additional agents arrived at the scene. Cervantes exited the vehicle and began kicking the agents who were attempting to arrest Contreras. During the altercation, Contreras bit and struck multiple agents. Both Contreras and Cervantes were eventually taken into custody. All four agents sustained injuries. [Case Number: 25-MJ-9300]
United States v. Benigno Armando Rios Pacheco, et al: On July 24, Benigno Armando Rios Pacheco and Janeth Karina Montoya Estrada were charged by criminal complaint with assaulting federal officers. Drug Enforcement Administration (DEA) agents were investigating Rios for being unlawfully present in the United States. During the course of their investigation, agents learned that Rios was also wanted in Mexico for the theft of a vehicle involving a firearm. DEA agents conducted a traffic stop on Rios, who complied with verbal commands and was placed in handcuffs without incident. Shortly thereafter, Montoya arrived at the scene with another individual. Montoya became aggressive toward the agents, approaching them closely and yelling. She then physically pushed a DEA agent. As agents attempted to place Montoya under arrest, she made erratic movements that resulted in injuries to several agents. Simultaneously, Rios began to resist by throwing his elbows and using his body weight, causing himself and one agent to fall to the ground. Both Rios and Montoya were eventually subdued and taken into custody. Two agents sustained injuries during the incident. [Case Number: 25-MJ-9327]
These cases are part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
A criminal complaint is a formal accusation of criminal conduct. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
