Aimer Alberto Alvaran Posada, 52, of Colombia, was sentenced today to 150 months in prison for his role in a cocaine trafficking conspiracy.

According to court documents, Alvaran Posada was a high-level member within the Western Bloc of Clan del Golfo (CDG), a Colombian paramilitary and multibillion-dollar transnational criminal organization that was designated on Dec. 16, 2025, by the Department of State as a Foreign Terrorist Organization (FTO) and a Specially Designated Global Terrorist (SDGT). CDG relies on cocaine trafficking to fund its paramilitary activities. In 2018, Alvaran Posada conspired with other CDG members to produce 500 kilograms of cocaine for sale to Mexican buyers, knowing, intending, and having reasonable cause to believe that the cocaine was destined to the United States. Specifically, Alvaran Posada obtained approval from the commander of CDG’s Northern Bloc, where the cocaine transaction would be conducted, and presided over multiple meetings to coordinate the cocaine transaction. Approximately 363 kilograms of cocaine were seized as part of the operation that led to the conviction of Alvaran Posada.

While engaged in this conspiracy, Alvaran Posada was informed by Dairo Antonio Úsuga David — the former leader of CDG — that he was being considered for commanding CDG’s Western Bloc, a promotion that would have given Alvaran Posada control over a vast network of subordinates, the authority to set cocaine prices, and the responsibility to decide who could produce and transport cocaine in his territory. Instead, Alvaran Posada was arrested in 2021 pursuant to his U.S. charges and subsequently extradited to the United States. He pleaded guilty to cocaine trafficking conspiracy on Aug. 27, 2025.

A Florida man appeared for the first time in federal court yesterday to face tax and false statement charges.

In July 2021, a federal grand jury returned a second superseding indictment charging Brian Nelson Booker, a former resident of Fort Lauderdale, Florida, with failing to file Reports of Foreign Bank and Financial Accounts (FBARs), filing false documents with the IRS, and making false statements.

According to the second superseding indictment, Booker, a former CPA whose business specialized in international trade, owned a cocoa trading company that was organized under the laws of the Republic of Panama. Booker allegedly operated that company from Venezuela, Panama and his former residence in Fort Lauderdale, Florida. For calendar years 2011 through 2013, Booker allegedly failed to disclose his interest in financial accounts located in Switzerland, Singapore and Panama on annual FBARs as required by law. Booker also allegedly filed individual income tax returns for the years 2010 through 2012 that did not report to the IRS all of Booker’s foreign bank accounts.

Booker is also charged with filing a false “Streamlined Submission” in conjunction with the IRS Streamlined Domestic Offshore Procedures. The IRS Streamlined Procedures allowed certain eligible taxpayers residing within the United States to voluntarily report to the IRS certain past disclosure failures. According to the second superseding indictment, Booker’s Streamlined Submission falsely claimed that his failure to report all income, pay all tax and submit all required information returns, such as FBARs, was due to non-willful conduct.

Booker allegedly left the United States in 2016 after learning about the criminal investigation against him. He lived in Russia but was never ordered to be extradited. In May 2025, Booker was arrested in Belarus, where he was detained and eventually ordered to be expelled. Booker returned to the United States on July 24th and was arrested at a Miami airport.

If convicted, Booker faces a maximum penalty of five years in prison for each count of failure to file an FBAR and false statements to the United States. He also faces a maximum penalty of three years in prison for each count of filing false documents with the IRS.

On April 7, the Department of Justice announced the creation of the National Fraud Enforcement Division (Fraud Division). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department’s work to combat fraud supports President Trump’s Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.

An indictment is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.

Yaroslav Shilkloper, 50, a dual citizen of Ukraine and Israel, was sentenced today to four years in prison for his participation in a conspiracy that utilized a sophisticated phony brokerage-business to scam U.S. citizens out of millions of dollars. Shilkloper was also ordered to pay a $250,000 fine and $1.43 million in restitution to his victims.

According to court documents and statements made in court, Shilkloper and his co-conspirators defrauded victims in the United States of more than $3 million dollars by promising high rates of return on investments made through their “K6 Investing,” “Neotron Holding LTD.,” and “Goldex Technology” companies. As part of the scheme, the defendant provided access to a digital platform that allowed victims to see what they believed were real-time investment performance data. The victims’ money, however, was never invested, but instead diverted and laundered through a series of bank accounts in Ukraine, Georgia, Hungary, Israel, Czech Republic, and elsewhere, all controlled by Shilkloper and his co-conspirators. When victims attempted to withdraw their money, they were prevented from doing so, threatened with legal action, or manipulated into sending more money to the fraud ring. 

Shilkloper is the first of three defendants charged in the case to be sentenced. He was extradited from Poland after being arrested there in 2023. Today’s U.S. forfeiture order adds to the $2.8 million already previously returned to the victims as a result of forfeiture proceedings against Shilkloper and co-conspirators in the Republic of Georgia.

Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division, U.S. Attorney Baxter Kruger for the Southern District of Mississippi, and Acting Special Agent in Charge Matt Wright of U.S. Immigration and Customs Enforcement Homeland Security Investigations (HSI) New Orleans Field Office made the announcement.

An El Paso, Texas, woman pleaded guilty today to smuggling unaccompanied alien children into the United States. 

According to court documents, Dianne Guadian, 33, and three other members of an alien smuggling organization brought unaccompanied alien children between the ages of five and 13 illegally into the United States from Juarez, Mexico, sometimes using candy laced with THC to sedate them during smuggling events. The drivers and their co-conspirators would then present U.S. documents to inspecting officers falsely claiming the documents belonged to the children, and that they were the parents of the children. Once inside the United States, the children were then transported to El Paso. During one smuggling event, a child was taken to a local hospital and diagnosed with THC poisoning.  One of Guadian’s co-defendants, Manuel Valenzuela, was sentenced on July 1 to five years in prison for his role in the child smuggling scheme.

“This defendant and her co-conspirators engaged in serious and dangerous conduct, which included giving THC laced gummies to children to sedate them while smuggling them from Mexico into the United States, all in order to make money,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “The smuggling of unaccompanied children can expose them to the additional crimes and societal ills of human trafficking and sexual assault. This robs them of their innocence and youth, and it must be stopped.”

“Dianne Guadian was just one conspirator in a sickening smuggling operation, toying with the lives of children by drugging them in order to bring them into the United States from Mexico,” said U.S. Attorney Justin R. Simmons for the Western District of Texas. “Fortunately, our partners at U.S. Customs and Border Protection (CBP) recognized something was off. Their keen instincts resulted in the successful medical treatment of THC-poisoned children and the arrests of the smugglers. While we will aggressively prosecute all alien smugglers, those who smuggle children and risk the lives of those children in the process, should be especially aware that their date with American justice is coming at the hands of prosecutors in the Western District of Texas.”

“Dianne Guadian’s actions were not only unscrupulous, they put innocent children in grave danger,” said Deputy Executive Associate Director Matthew Millhollin of U.S. Immigration and Customs Enforcement Homeland Security Investigations (HSI). Human smuggling is never a victimless crime. Smugglers routinely expose vulnerable people, including children, exploitation and life-threatening risk. HSI is committed to holding individuals like Guadian accountable and dismantling criminal organizations that profit from the desperation and suffering of others.”

“Criminal human smugglers exploit vulnerable children in horrific ways,” said Chief Patrol Agent Jesse Munoz of U.S. Border Patrol El Paso Sector. “I am glad our Border Patrol agents investigating this case were able to contribute to the successful prosecution of a criminal who will be held accountable for this terrible crime.”

Guadian pleaded guilty to four counts of aiding and abetting bringing of aliens without authorization for profit. She faces a minimum penalty of five years in prison and a maximum penalty of 15 years in prison. A sentencing date has not yet been set. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

HSI El Paso and U.S. Border Patrol (USBP) led investigative efforts, with substantial assistance from HSI’s Human Smuggling Unit in Washington, D.C. and CBP’s National Targeting Center International Interdiction Task Force. 

Trial Attorney Bethany Allen of the Criminal Division’s Human Rights and Special Prosecutions Section and Assistant U.S. Attorney Adam Hines for the Western District of Texas are prosecuting the case.

The indictment and plea announced today were coordinated and prosecuted by Joint Task Force Alpha (JTFA), the Department’s lead effort in combating high-impact human smuggling and trafficking committed by cartels and Transnational Criminal Organizations (TCOs). JTFA also leads and supports U.S. Attorneys’ Offices (USAOs) in the prosecution of crimes related to unaccompanied alien children (UACs). A highly successful partnership between the Department of Justice and the Department of Homeland Security (DHS), JTFA investigates and prosecutes human smuggling and trafficking and related immigration crimes that impact public safety and border security. JTFA’s mission is to target the leaders and organizers of Cartels and TCOs involved in human smuggling and trafficking throughout the Americas. The Attorney General has elevated and expanded JTFA to target the most prolific and dangerous human smuggling and trafficking groups operating not only in Mexico and the Northern Triangle countries of Guatemala, El Salvador, and Honduras, but also in Canada, the Caribbean and the maritime border, and elsewhere. Led by the Criminal Division’s Human Rights and Special Prosecutions Section and supported by the Money Laundering, Narcotics and Forfeiture Section, the Office of International Affairs, and the Office of Enforcement Operations, among others, JTFA has dedicated Assistant U.S. Attorneys from the Southern District of California; District of Arizona; District of New Mexico; Western and Southern Districts of Texas; Southern District of Florida; Northern District of New York; and District of Vermont. JTFA also partners with other USAOs throughout the country and supports high-priority cases in any district. All JTFA cases rely on substantial law enforcement resources from DHS, including HSI and CBP/USBP and Office of Field Operations, as well as FBI and other law enforcement agencies. To date, JTFA’s work has resulted in more than 465 domestic and international arrests of leaders, organizers, and significant facilitators of alien smuggling and/or trafficking; more than 424 U.S. convictions; and more than 368 significant jail sentences imposed, and forfeitures of substantial assets.

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 Project Safe Neighborhoods (PSN).

The ex-wife and current partner of a leader of the Mexican drug trafficking organization known as Los Cuinis pleaded guilty today to willfully violating counternarcotic sanctions. Los Cuinis is closely aligned with the Cártel de Jalisco Nueva Generación (CJNG), which the State Department designated as a foreign terrorist organization in February 2025. This case is part of the Homeland Security Task Force (HSTF) initiative.

According to court documents, Wendy Dalaithy Amaral Arevalo, 45, of Mexico, committed criminal violations of the Foreign Narcotics Kingpin Act (Kingpin Act) by engaging in transactions and dealings in property with IMG Academy, a preparatory school and athletic training facility headquartered in Bradenton, Florida, that Amaral’s child attended. On Aug. 19, 2015, the U.S. Department of the Treasury Office of Foreign Assets Control (OFAC) sanctioned Amaral Arevalo for assisting the international narcotics trafficking activities of Los Cuinis, a sanctioned drug cartel. Despite Amaral Arevalo’s OFAC designation, which prohibited her from engaging in transactions or dealings within the U.S. financial system, Amaral Arevalo entered into contracts with IMG Academy for her child to attend the school and arranged for $504,497.48 in tuition payments.

On July 21, 2023, Amaral Arevalo’s ex-husband and current partner, Gerardo Gonzalez Valencia, was sentenced to life in prison for conspiring to distribute tonnage quantities of cocaine for importation into the United States. On Feb. 12, 2026, OFAC announced a $1.72 million settlement with IMG Academy for entering into yearly tuition agreements with Specially Designated Nationals (SDNs) sanctioned for their ties to a sanctioned Mexico-based drug cartel and receiving and processing payments pursuant to those agreements.

“Wendy Dalaithy Amaral Arevalo willfully violated U.S. counternarcotic sanctions by funneling over half a million dollars in illicit drug proceeds as tuition payments through IMG Academy in Bradenton, Florida, despite being prohibited from engaging in transactions within the U.S. financial system,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “The Kingpin Act exists to cut off foreign narcotics traffickers, their businesses, and their operatives from engaging in transactions within the U.S. financial system, and prevents them from using American institutions to receive or move drug money. The Criminal Division will use every tool available to dismantle drug cartels, protect the American people, and ensure financial transactions in the United States are free of sanctioned drug proceeds.”

“Wendy Dalaithy Amaral Arevalo exploited a school and training facility — a place families trust to invest in their children’s futures — as a vehicle to funnel millions in illicit drug proceeds for CJNG, one of the Western Hemisphere’s most violent and destabilizing drug cartels,’’ said Administrator Terrance C. Cole of the Drug Enforcement Administration (DEA). “Her guilty plea exposes the calculated audacity and sophisticated reach of cartel financial networks operating inside the United States. DEA, alongside our law enforcement partners, remains committed to pursuing the leaders, financiers, and enablers who sustain these terrorist enterprises.”

Amaral Arevalo faces a maximum penalty of 10 years in prison and a fine of $10 million. Sentencing has been set for Dec. 2.

An illegal alien from Guatemala pleaded guilty today to illegal reentry after previously being deported. 

According to federal and state court documents, Bayron Leopoldo Perez Batres, 64, who resided in Beltsville, Maryland, unlawfully reentered the United States after having been previously removed. On Sept. 6, 2024, Perez Batres was arrested in Maryland on state charges relating to sexual abuse of a minor. After his arrest on state charges, it was established that he was illegally present in the United States and that he has been previously removed to Guatemala on three separate occasions – in January 1996, September 2009, and May 2010. He was charged with illegal reentry in the present case on Nov. 13, 2025. He pleaded guilty to state sexual abuse charges on Sept. 2, 2025 and was sentenced to 25 years in prison in October 2025.
