Court documents indicate that members of an alien smuggling organization illegally brought unaccompanied children, ages five to 13, from Juarez, Mexico, into the United States between approximately May 1 and Oct. 17, 2024.

The organization allegedly recruited drivers to transport the children to a port of entry, where they would present U.S. documents and falsely claim to be the children’s parents. Once inside the U.S., the children were transported to El Paso.

Valenzuela’s role in the scheme involved picking up the children after they were smuggled into the country and providing cash payments of $900 to the drivers for each minor, according to the complaint.

Authorities detailed a particularly disturbing aspect of the operation, noting that during at least one smuggling event, the children were given gummy candies containing marijuana to sedate them. One child was later taken to a local hospital and diagnosed with THC poisoning.

They found a conversation between Dianne and a person believed to be Susana Guadian. The selected conversation is from October 17, 2024.  (Source: U.S. V. GUADIAN ET. AL., WESTERN DISTRICT OF TEXAS, CASE NO: EP-25-M-04855-MAT, FILED 08/29/2025)

What they're saying:

"These defendants allegedly risked the lives of children by using drug-laced candy to keep them quiet while being smuggled into the United States," Acting Assistant Attorney General Matthew R. Galeotti said following the initial charges. "Targeting children in this way is especially dangerous and cruel."

The case is being investigated by Homeland Security Investigations El Paso and U.S. Border Patrol. It is part of the Justice Department's Joint Task Force Alpha (JTFA) and Operation Take Back America initiatives, which target cartels and transnational criminal organizations involved in human smuggling and trafficking.

"When these cartels and the Alien Smuggling Organizations with which they partner see children, they see dollar signs," U.S. Attorney Simmons said previously. "This case shows that cartels and alien smuggling organizations care nothing for the wellbeing of the people they move into the United States. They only care about enriching themselves."

What's next:

A federal district court judge will determine Valenzuela’s final sentence at a later date after considering the U.S. Sentencing Guidelines.
