Operation Take Back America: 271 Immigration Cases Filed in Texas
Federal prosecutors in Houston announced the filing of 271 new criminal cases in a single week, targeting immigration and border security violations across the Southern District of Texas. The charges, made public on May 22, stem from a multi-agency effort under the nationwide Operation Take Back America, and include a truck driver accused of smuggling 42 people in a locked, unventilated trailer, as well as repeat offenders with prior narcotics and violent crime convictions. Acting U.S. Attorney John G.E. Marck confirmed that 249 illegal aliens were charged with unlawfully being in the country, 19 individuals were charged with human smuggling, and additional cases involved other immigration crimes.

The Scope of This Week’s Charges
The 271 cases, filed from May 15 to May 21, represent one of the largest weekly immigration-related dockets in the district in recent memory. The Southern District of Texas, which spans 43 counties and over 10 million residents, has long been a focal point for federal immigration prosecutions. According to the U.S. Attorney’s Office, 182 of the 249 illegal alien defendants were charged with illegal reentry after prior deportations, while 67 faced illegal entry charges. Prosecutors say most of those charged already have criminal histories that include narcotics offenses, immigration violations, and violent crimes.
The remaining 22 cases cover a range of immigration crimes, including human smuggling and related offenses. The week’s activities also included two guilty verdicts in separate reentry trials, and the sentencing of a previously deported sex offender to 40 months in prison. Officials said the surge in prosecutions reflects both enhanced border enforcement and interior enforcement actions, with coordination among multiple federal, state, and local agencies.
Human Smuggling Attempt: 42 People Found in a Locked Trailer
One of the most serious cases announced involved Juan Nasario-Reyes, an out-of-state truck driver who was arrested after an alleged human smuggling attempt at a checkpoint. According to the criminal complaint, Nasario-Reyes arrived at the checkpoint on May 16 and told authorities his vehicle was empty. A K-9 unit alerted, and a subsequent search revealed four illegal aliens concealed inside the cab of the truck. An additional 38 people were discovered locked inside the trailer, which had been latched from the outside. Investigators recorded an interior temperature of approximately 92.5 degrees.
The complaint says 13 of the 42 illegal aliens are now facing separate illegal entry or reentry charges, while the remaining 29 are expected to be immediately removed from the country. Nasario-Reyes has been charged with human smuggling offenses. Authorities pointed to the dangerous conditions inside the trailer—heat, lack of ventilation, and the fact that the door could not be opened from the inside—as factors that make the case particularly serious. The incident highlights the risks that human smuggling operations pose to the people being transported, and the U.S. Attorney’s Office said it will continue to prioritize such cases.
Repeat Offenders: Prior Convictions for Narcotics and Violent Crimes
Among the dozens of illegal reentry cases, three Mexican nationals stand out for their significant criminal histories. Santos Rivera-Garcia, Faustino Soto, and Genaro Perez-Alonso were all allegedly found unlawfully in the United States despite previous removals and serious prior convictions. Rivera-Garcia had a prior felony conviction for illegal reentry and was sentenced to 63 months in federal prison in 2022, according to court records. He was removed from the country on April 24 of this year, but authorities say they discovered him near Mission, Texas, less than a month later. His case underscores how quickly some individuals attempt to return after deportation.
Faustino Soto and Genaro Perez-Alonso were also located near Escobares and Mission, respectively. Both have prior narcotics convictions and had been sentenced to at least 10 years in prison before being removed from the United States. Court documents indicate that none of the three men had legal authorization to reenter the country at the time of their arrest. If convicted of the current illegal reentry charges, each could face up to 20 years in federal prison. Federal law allows for enhanced penalties when the defendant has prior aggravated felony convictions.
Guilty Verdicts: Two Illegal Reentry Trials
The same announcement included two guilty verdicts from separate federal trials in Houston and Corpus Christi. In Houston, a jury deliberated for less than 30 minutes before convicting Mexican national Eduardo Aguilera-Gallardo of illegal reentry. Aguilera-Gallardo had argued that he was kidnapped and forced to return to the United States against his will, but testimony showed that neither he nor his family ever sought help from law enforcement in Mexico or the U.S. after his previous removal. Investigators found him in Houston after a deportation officer had escorted him across the border in Laredo following his removal order.
In Corpus Christi, a jury needed even less time—fewer than 10 minutes—to convict Jose Leandro Juarez-Rivas, also from Mexico. Authorities had identified him on a commercial bus on February 18 with no legal authorization to be in the country. The defense argued that Juarez-Rivas was unaware he had been ordered removed or that he was barred from reentering. The jury rejected those claims and returned a guilty verdict. Both men now await sentencing, and their convictions become part of their permanent criminal records.
Sentencing of a Previously Deported Sex Offender
In another Houston case, Jose Angel Martinez Menjivar, a Salvadoran national, was ordered to serve 40 months in federal prison for illegal reentry. Martinez Menjivar had been deported in 2022 after serving time for a prior illegal reentry conviction and indecent assault by touching. Despite that removal, authorities located him in Houston on July 9, 2025. Because of his sex offense conviction and previous immigration violations, his reentry was treated as a felony under federal law. The 40-month sentence reflects the seriousness with which federal courts view repeat immigration offenders, especially those with violent or sex offense backgrounds.
What Is Operation Take Back America?
Operation Take Back America is a nationwide initiative launched by the Department of Justice to direct federal resources toward immigration enforcement, cartel disruption, and the prosecution of violent crime linked to transnational criminal organizations. The Southern District of Texas has been a key participant, filing hundreds of cases in recent months. According to the U.S. Attorney’s Office, the operation aims to “repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations and protect our communities from the perpetrators of violent crime.”
Under this operation, prosecutors are encouraged to pursue both border-area and interior enforcement actions, targeting not only those who cross the border illegally but also those who are found inside the United States with prior deportations or serious criminal records. The initiative calls on all available federal law enforcement agencies—including ICE, Border Patrol, DEA, FBI, U.S. Marshals, and ATF—to work alongside state and local partners. The large number of cases filed in a single week demonstrates the operation’s intensity in one of the nation’s busiest districts.
How the Legal Process Works: Charges, Complaints, and Presumption of Innocence
All of the newly filed cases are based on criminal complaints, which set out the allegations and give a federal magistrate judge the basis to issue arrest warrants and set bail. A criminal complaint is not a finding of guilt—it is simply the starting point in a federal criminal case. The U.S. Attorney’s Office emphasizes that every defendant is presumed innocent unless and until proven guilty in a court of law. Once a complaint is filed, the case proceeds through initial appearances, detention hearings, probable cause determinations, and eventual grand jury review or presentation of an indictment.
Illegal reentry, the most common charge in this round of prosecutions, is governed by federal statute 8 U.S.C. § 1326. For a person with an aggravated felony conviction, the maximum prison term can reach 20 years. For those without such priors, the maximum is typically 10 years. The charging decisions made by federal prosecutors reflect the specific facts of each case, including the defendant’s criminal history, the date and manner of reentry, and whether the person presented any national security or public safety threat. By law, defendants have the right to a trial by jury, and many of the reentry cases have resulted in swift jury verdicts this year.
Multi-Agency Coordination and the Role of Federal Partners
The week’s cases were referred or supported by a broad coalition of agencies, including ICE Homeland Security Investigations (HSI), ICE Enforcement and Removal Operations (ERO), U.S. Border Patrol, the Drug Enforcement Administration (DEA), the FBI, the U.S. Marshals Service, and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). State and local law enforcement also played an essential role in locating and apprehending suspects across the district’s vast geographic area, which covers cities from Houston to Laredo, Brownsville to Galveston.
Assistant U.S. Attorneys from all seven divisions—Houston, Galveston, Victoria, Corpus Christi, Brownsville, McAllen, and Laredo—handled the cases. The U.S. Attorney’s Office said this level of cooperation is designed to maximize the impact of the operation, combining federal investigative resources with the local knowledge of municipal and county agencies. The immediate goal, according to the announcement, is to disrupt smuggling networks, remove individuals with serious criminal records, and deter future illegal border crossings.
Public Safety Implications and What Remains Unclear
Federal authorities framed the surge in prosecutions as a direct response to both border security and community safety concerns. By charging individuals who have been previously deported for serious crimes, and by targeting smuggling operations that endanger lives, the government aims to send a signal that reentry after removal and the facilitation of illegal immigration will be met with significant consequences. At the same time, the sheer volume of cases raises questions about how the district’s courts, detention facilities, and legal resources will handle the caseload over the coming months.
Several aspects remain unclear, however. The announcement did not specify how many of the defendants are in federal custody versus being sought by authorities, nor did it detail the expected timelines for trials or plea negotiations. The human smuggling case involving the truck driver is ongoing, and the defendants have not yet entered pleas. Additionally, officials have not publicly released data on outcomes of previous weeks’ filings under Operation Take Back America—information that would help the public understand whether the high number of charges is translating into convictions and long-term sentences. Any such data would be important for evaluating the effectiveness of the policy.
