Mexican National Sentenced to Prison for Drugging and Smuggling Unaccompanied Alien Children into the United States

A Mexican national was sentenced today to five years in prison for smuggling children into the United States from Mexico.

According to court documents, Manuel Valenzuela, 35, and 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, one of the children was taken to a local hospital and diagnosed with THC poisoning.

"Needing to sedate children with THC under the guise of giving them candy, shows just how heinous crimes like this are," said Assistant Attorney General A. Tysen Duva of the Justice Department's Criminal Division. "Smuggling unaccompanied children into the country, pretending to be their parents, and then lying to U.S. immigration officials shows the lengths to which criminals like this will go to smuggle children across our borders. The Criminal Division and our law enforcement partners will put an end to this conduct. Protecting children and keeping our borders safe go hand-in-hand."

"We fight every day in the Western District of Texas to ensure that the people and organizations responsible for heinous crimes like this are brought to justice," said U.S. Attorney Justin R. Simmons for the Western District of Texas. "Criminal organizations like this one would be well advised to think twice before engaging in this type of crime. Our message to them is this: we will find you, we will secure a conviction, and we will ensure you are removed from society for as long as possible."

"Drug traffickers who exploit children as part of their criminal schemes show total disregard for human life and safety," said Acting Special Agent in Charge Ryan G. McRae of U.S. Immigration and Customs Enforcement Homeland Security Investigations (HSI) El Paso. "Using THC-infused candy to facilitate the smuggling of children across the border into the United States is reprehensible and cruel and puts vulnerable minors at serious risk. HSI will relentlessly pursue transnational criminal organizations responsible for these heinous tactics and bring them to justice."

Valenzuela pleaded guilty to one count of conspiracy to transport aliens, three counts of bringing aliens without authorization for financial gain, and one count of aiding and abetting on Nov. 10, 2025.

HSI El Paso and U.S. Border Patrol led investigative efforts, with substantial assistance from HSI's Human Smuggling Unit in Washington, D.C. and Customs and Border Protection'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 investigation and indictment were supported 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). 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. Attorney-detailees 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 U.S. Attorney's Offices 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 Customs and Border Protection, Border Patrol and Office of Field Operations as well as FBI and other law enforcement agencies. To date, JTFA's work has resulted in more than 464 domestic and international arrests of leaders, organizers, and significant facilitators of alien smuggling and/or trafficking; more than 414 U.S. convictions; and more than 360 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).
