SAN ANTONIO – Acting United States Attorney Margaret Leachman for the Western District of Texas announced today, that federal prosecutors in the district filed 334 new immigration and immigration-related criminal cases from May 16 through May 22.

Among the new cases, Salvadoran felon Erick Douglas Serrano-Aleman was arrested by Van Horn Border Patrol agents for being an illegal alien present in the U.S. A criminal complaint indicates Serrano-Aleman was previously convicted of transporting and selling a controlled substance as well as accessory. In 2004, he was convicted for illegal re-entry in Nogales, Arizona. Serrano-Aleman has been deported twice and allegedly claims to be a member of the Sureño 13 gang.

In El Paso, multiple alleged human smugglers were arrested, including U.S. citizen Ernesto Covarrubias and Tanya Joselyn De La Paz-Nunez, a Mexican national in possession of a legal B1/B2 Visa Border Crossing Card. Covarrubias, as the vehicle driver, and De La Paz-Nunez allegedly picked up five illegal aliens inside a pecan orchard near the Tornillo Port of Entry, intending to transport them to a stash house.

U.S. citizen Gabriela Ivon Trejo-Gonzalez was arrested after U.S. Border Patrol agents allegedly observed six individuals crawl through a breach in the border fence near the Paso Del Norte Port of Entry and board Trejo-Gonzalez’s vehicle. The defendant allegedly drove away at a high rate of speed and continued in an attempt to evade law enforcement before becoming inoperable. Trejo-Gonzalez allegedly claimed she would be paid $500 per alien. She was convicted for alien smuggling in New Mexico in June 2023 and probation violation in October 2023.

Juan Pedro Carmona-Cerritos, a Mexican felon, was arrested in El Paso and charged with illegal re-entry. Carmona-Cerritos was last removed from the U.S. in April 2009. He was previously convicted of child abuse in 2004 and second degree reckless homicide in 2005 in Waukesha, Wisconsin, for which he was sentenced to a total of approximately three years in prison. Guatemalan national Ramon Cortes-Velasquez was also arrested for illegal re-entry in El Paso, having been convicted of assault causing bodily injury to a family member in February and removed from the U.S. to Guatemala in March.

Mexican nationals Jose Rolando Arenas-Aleman and J Angel Nava-Sanchez were arrested near Del Rio. According to court documents, Arenas-Aleman was arrested May 14 by U.S. Border Patrol agents for being an illegal alien present in the United States. He had previously been removed to Mexico for the second time through Laredo on Sept. 6, 2024 following his second conviction for Driving While Intoxicated. Nava-Sanchez was arrested May 15 after allegedly crossing the Rio Grande River near Del Rio. Nava-Sanchez was convicted twice in Tarrant County. He was found sentenced to 45 days in jail for a DWI in July 2022 and 29 days in jail in August 2018, for assault causing bodily injury to a family member.

A U.S. citizen was arrested May 19 during a traffic stop on Highway 85 near Dilley. A criminal complaint alleges that Alex Guadalupe Nieto was the driver of a vehicle transporting six illegal aliens. The complaint alleges that Nieto stated he and another individual drove from Houston, picking up the six illegal aliens on the side of the road, and that he had expected to be paid $500.00 to transport the aliens.

In Austin, Mexican national Juan Robledo-Trevino aka Octavio Garcia-Sanchez was taken into federal custody by Immigration and Customs Enforcement after being arrested and sentenced to 10 days in the Travis County Jail for failure to identify. Robledo-Trevino has two prior convictions for illegal re-entry, and four previous DWI convictions. He’s been removed from the U.S. to Mexico four times, most recently in November 2016, and voluntarily returned to Mexico twice.

Mexican national Jose Hernandez-Martinez was taken into ICE custody in Austin where he had been arrested for his second DWI and spent 20 days in the Travis County Jail. Hernandez-Martinez has a prior illegal entry conviction along with convictions for theft and assault causing bodily injury to a family member. He voluntarily returned to Mexico in 2006, and has been twice removed from the U.S.

Edgar Aguilar-Mejia, a Guatemalan national, was also taken into ICE custody in Austin. Aguilar-Mejia was convicted twice in 2023 for illegal re-entry and has been removed from the U.S. three times before, as recent as April 2024.

These cases were referred or supported by federal law enforcement partners, including Homeland Security Investigations (HSI), Immigration and Customs Enforcement’s Enforcement and Removal Operations (ICE ERO), 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), with additional assistance from state and local law enforcement partners.

The U.S. Attorney’s Office for the Western District of Texas comprises 68 counties located in the central and western areas of Texas, encompasses nearly 93,000 square miles and an estimated population of 7.6 million people. The district includes three of the five largest cities in Texas—San Antonio, Austin and El Paso—and shares 660 miles of common border with the Republic of Mexico.

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).

Indictments and criminal complaints are merely allegations and all defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.

U.S. Attorney’s Office Filed 134 Border-Related Cases This Week

Source: Office of United States Attorneys

SAN DIEGO – Federal prosecutors in the Southern District of California filed 134 border-related cases this week, including charges of bringing in aliens for financial gain, reentering the U.S. after deportation, and importation of controlled substances.

The U.S. Attorney’s Office for the Southern District of California is the fourth-busiest federal district, largely due to a high volume of border-related crimes. This district, encompassing San Diego and Imperial counties, shares a 140-mile border with Mexico. It includes the San Ysidro Port of Entry, the world’s busiest land border crossing, connecting San Diego (America’s eighth largest city) and Tijuana (Mexico’s second largest city).

In addition to reactive border-related crimes, the Southern District of California also prosecutes a significant number of proactive cases related to terrorism, organized crime, drugs, white-collar fraud, violent crime, cybercrime, human trafficking and national security. Recent developments in those and other significant areas of prosecution can be found here.

A sample of border-related arrests this week:

  • On May 16, Elizabeth Janeth Ramirez-Martinez, a U.S. citizen, was arrested and charged with Bringing in Aliens for Financial Gain. According to a complaint, Ramirez-Martinez was stopped at the Otay Mesa Port of Entry by Customs and Border Protection officers, who found a Vietnamese national crammed into a compartment in the dash of her vehicle. The undocumented immigrant told officers that before they made their way to the border, the defendant had placed him in the compartment and secured it using screws.
  • On May 19, Fernanda Barrios Monzon, a legal permanent resident of the U.S., was arrested and charged with Bringing in Unlawful Aliens without Presentation and Importation of a Controlled Substance. According to a complaint, the defendant drove her vehicle through the San Ysidro Port of Entry but was stopped when a Customs and Border Protection officer noticed a man lying on the floor of the vehicle, under the feet of the defendant’s children. The officer further discovered 271 pounds of methamphetamine hidden throughout the vehicle.
  • On May 20, Gustavo Hernandez Oliveros, was arrested and charged with Deported Alien Found in the U.S. According to a complaint, Border Patrol agents located Hernandez Oliveros hiding in brush about two miles north of the border and two miles east of the Otay Mesa Port of Entry. He was previously deported in November 2018.

Also recently, a number of defendants with criminal records were convicted by a jury or sentenced for border-related crimes such as illegally re-entering the U.S. after previous deportation. Here are a few of those cases:

  • On May 23, Jair Valdez-Hernandez, a Mexican national who was previously convicted of felony attempted carjacking in 2017, was sentenced in federal court to 10 months in custody for illegally entering the U.S. After illegally reentering the U.S., in July 2024, Valdez-Hernandez was convicted of corporal injury to a spouse/cohabitant and within the two months following that conviction was arrested twice for violating domestic violence protective orders.
  • On May 23, Rogelio Herrera-Rodriguez, a Mexican national who was previously convicted of voluntary manslaughter and corporal injury to a spouse causing great bodily injury and removed from the United States, was sentenced in federal court to 24 months for again reentering the U.S. illegally.
  • On May 23, Sacramento Sagrero-Pahua, a Mexican national, was sentenced in federal court to 36 months in custody for bringing aliens to the United States for financial gain. On August 26, 2023, Sagrero-Pahua guided a group of eight illegal aliens into the United States near Otay Mountain before being caught by Border Patrol agents. Among the group Sagrero-Pahua guided was an armed guard, who brought a gun with him to protect the group as it traveled toward the U.S.-Mexico border.
  • On May 19, 2025, Oscar Eduardo Audelo-Rodriguez, a Mexican national, who admitted to fleeing border patrol agents by boat in Mission Bay, was sentenced in federal court to 8 months in custody for alien smuggling.

Pursuant to the Department’s Operation Take Back America priorities, federal law enforcement has focused immigration prosecutions on undocumented aliens who are engaged in criminal activity in the U.S., including those who commit drug and firearms crimes, who have serious criminal records, or who have active warrants for their arrest. Federal authorities have also been prioritizing investigations and prosecutions against drug, firearm, and human smugglers and those who endanger and threaten the safety of our communities and the law enforcement officers who protect the community.

The immigration cases were referred or supported by federal law enforcement partners, including Homeland Security Investigations (HSI), Immigration and Customs Enforcement’s Enforcement and Removal Operations (ICE ERO), Customs and Border Protection, 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), with the support and assistance of state and local law enforcement partners.

Guatemalan Drug Trafficker Sentenced to 14 Years

Source: Office of United States Attorneys

SAN DIEGO – Arnoldo Oswaldo Vargas-Samayoa, a Guatemalan national, was sentenced in federal court today to ­14 years in prison for managing a cocaine trafficking organization that smuggled more than 1,000 pounds of cocaine into the United States from Guatemala.

Following his surrender to U.S. authorities in June 2024 at Los Angeles International Airport, Vargas-Samayoa pleaded guilty to charges of conspiracy to import cocaine that were filed in January 2020.

In imposing sentence, U.S. District Judge Cathy Ann Bencivengo noted that Vargas-Samayoa was a “manager of a very extensive international drug ring” and money laundering effort who did not make a “mistake” but rather “chose a lifestyle.”

Vargas admitted he sourced the cocaine from two different Guatemalan suppliers and coordinated delivery to a Mexico-based drug trafficker. Vargas and the Mexico-based trafficker arranged for the drugs to be hidden in vehicles and smuggled into the United States through ports of entry in Southern California and Southern Texas.

Vargas, whose communications were being intercepted by law enforcement, messaged with the trafficker while cocaine loads were being moved into the United States to confirm the drugs were successfully smuggled. Once in the United States, some of that cocaine was moved to the Chicago area for further distribution. Vargas received a commission of $1,000 U.S. dollars for each kilogram of cocaine he delivered to the Mexico-based trafficker.

“Cocaine continues to be a dangerous and highly addictive drug with devastating consequences for individuals and communities,” said U.S. Attorney Adam Gordon. “We remain committed to dismantling the entire supply chain—from powerful cartel leaders to street-level dealers—and ensuring that those responsible are held accountable.”

“This sentencing sends the message that those who traffic dangerous drugs into our country will be held accountable,” said Shawn Gibson, special agent in charge for HSI San Diego. “Thanks to the outstanding investigative work and strong domestic and international law enforcement partnerships, we were able to disrupt a key supply line of a major drug trafficking network. We remain committed to targeting high-level drug trafficking organizations and keeping deadly narcotics, like cocaine, out of our communities.”

The U.S. Attorney’s office has previously convicted, and the court has sentenced, multiple couriers attempting to smuggle narcotics for the same drug trafficking organization as well as individuals engaged in related money laundering efforts (see list below). Through the related investigation of this matter, law enforcement has seized more than 1,000 kilograms of cocaine, more than $2 million in bulk currency, and firearms.     

Vargas’ father, Arnoldo Vargas Estrada, is the former mayor of Zacapa, Guatemala who was convicted by a jury in the Eastern District of New York in Case No. 90cr00855-SJF of five counts related to the importation of narcotics. He was sentenced to 365-months in custody. Vargas Estrada was one of the first Guatemalan drug traffickers to be extradited to the United States in the early 1990’s. He was released in 2017, returned to Guatemala, and then reelected as mayor of Zacapa holding that position until 2024.

This case is 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).

This case is the result of ongoing efforts by the Organized Crime Drug Enforcement Task Force (OCDETF), a partnership that brings together the combined expertise and unique abilities of federal, state and local law enforcement agencies. The principal mission of the OCDETF program is to identify, disrupt, dismantle and prosecute high-level members of drug trafficking, weapons trafficking and money laundering organizations and enterprises.

This case is being prosecuted by Assistant U.S. Attorney Larry Casper.

Spokane, Washington – The United States’s Attorney’s Office and the City of Spokane jointly announced today the appointment of a Special Assistant United States Attorney (SAUSA) for the Eastern District of Washington. The SAUSA, Annika Tangvald, will prosecute cases in federal court relating to illegal narcotics impacting the City of Spokane. Ms. Tangvald was sworn into office by Acting United States Attorney Rich Barker on May 19, 2025.

In making this announcement, Acting U.S. Attorney Barker reiterated his office’s commitment to combating the opioid epidemic. “We see the impact of fentanyl and other drugs in almost every case we prosecute – including violent crime, firearms trafficking, prosecution of transnational gangs and cartels, and even in some of our fraud and human trafficking cases.  Having a dedicated prosecutor for these cases allows the U.S. Attorney’s Office to bring more cases specifically focused on the City of Spokane.  SAUSA Tangvald, who I worked with as an AUSA in this office, is a talented lawyer and she will be working with some of the finest prosecutors in the United States to ensure those who distribute large amounts of drugs into the Spokane community are held responsible.”  Acting U.S. Attorney Barker added, “I am so grateful to the City for their collaboration to make this joint vision a reality.”

“The City of Spokane Prosecutor’s Office is committed to a multi-prong approach to end the fentanyl epidemic our community faces,” stated Justin Bingham, Prosecutor for the City of Spokane. “Partnering with the U.S. Attorney’s Office will greatly strengthen our current efforts to hold drug-related offenders accountable. I’m excited to see the positive impacts this joint position will bring to Spokane.”

“Special Assistant U.S. Attorney Tangvald will help fill a critical gap in our system. Her role in prosecuting fentanyl-related crimes is a vital step forward in our fight against the opioid crisis,” Mayor Lisa Brown said. “With dedicated resources and sharper focus, this move will protect our community, hold traffickers accountable, and ultimately save lives.”

Two Texas Residents Operating a Visa Racket Indicted for Visa Fraud, Money Laundering, and RICO Conspiracy

Two Texas residents, Abdul Hadi Murshid, 39, and Muhammad Salman Nasir, 35, both originally from Pakistan, a law firm, and a business entity were charged by indictment with conspiracy to defraud the United States, visa fraud, money laundering conspiracy, and Racketeering Influenced and Corrupt Organization Act (RICO) conspiracy, announced Acting United States Attorney for the Northern District of Texas Chad E. Meacham.  Murshid and Nasir were also charged with unlawfully obtaining and attempting to obtain United States citizenship.

According to the indictment, Abdul Hadi Murshid, Muhammad Salman Nasir, the Law Offices of D. Robert Jones PLLC, and Reliable Ventures, Inc. engaged in a scheme to commit visa fraud to enrich themselves and others, and to cause individuals to fraudulently obtain entry into and immigration status in the United States.  It is alleged that Murshid, Nasir, and others submitted and caused to be submitted false and fraudulent visa applications for individuals who were not United States citizens (hereinafter referred to as “visa seekers”), and applications to adjust status of the visa seekers so the visa seekers could enter and remain in the United States.

“These defendants are charged with engaging in extensive measures to hide a massive, multi-year, immigration fraud scheme through which they reaped substantial personal financial gain,” said Acting U.S. Attorney Chad E. Meacham.  “Pursuing criminal charges to deter and punish this type of flagrant disregard for the lawful immigration process is a top priority of this Office.”

“The defendants allegedly oversaw an international criminal enterprise for years that repeatedly undermined our nation’s immigration laws. These laws are necessary to protect national security and safeguard the lawful immigration process,” said FBI Dallas Special Agent in Charge R. Joseph Rothrock. “The FBI and our law enforcement partners will hold any individual accountable that misuses their position of trust for personal profit.” 

As part of the scheme, the indictment alleges that the defendants exploited the EB-2, EB-3, and H-1B visa programs.  Specifically, the defendants caused classified advertisements to be placed in a daily periodical for non-existent jobs.  These advertisements were placed in order to satisfy a Department of Labor (“DOL”) requirement to offer the position to United States citizens before hiring foreign nationals.  Once they received the fraudulently obtained certification for from the Department of Labor, the defendants filed a petition to the U.S. Citizenship and Immigration Services (“USCIS”) to obtain an immigrant visa for the visa seekers.  At the time the petitions were submitted, the defendants also submitted an application for legal permanent residence so that the visa seekers could also obtain a green card.  According to the indictment, to make the non-existent jobs look legitimate, the defendants received payment from visa seekers, then returned a portion of the money back to the visa seekers as purported payroll. 

The defendants made their initial appearances before U.S. Magistrate Judge Rebecca Rutherford on May 23, 2025, and the government moved for their detention. The detention hearings are scheduled for May 30, 2025, before U.S. Magistrate Judge Brian McKay.
An indictment is merely an allegation of criminal conduct, not evidence.  Like all defendants, Murshid, Nasir, and the business entities are presumed innocent until proven guilty in a court of law. 

If convicted, the defendants face up to 20 years in federal prison.  Murshid faces denaturalization if convicted of unlawfully obtaining and attempting to obtain his United States citizenship.

The Federal Bureau of Investigation conducted the investigation.  The Department of Homeland Security – Homeland Security Investigations, U.S. Citizenship and Immigration Services, the Department of State Diplomatic Security Service, and the Department of Labor Office of Inspector General provided significant assistance to the investigation. Assistant U.S. Attorneys Ted Hocter, Tiffany H. Eggers, and Jongwoo Chung are prosecuting the case.
