DEA agents in South Texas found more than $500,000 in cash hidden inside a semi truck. Some reports put the total over $600,000. Texas Department of Public Safety troopers helped agents stop the truck. DEA announced the seizure this week, though the agency has not said exactly when the stop itself happened.

Agents with the DEA's McAllen office made the stop with DPS troopers. They found the cash packed in bulk inside the truck. DEA says the money is likely tied to drug cartels working in the area. That is what agents believe right now. DEA has not said the cartel link is proven in court.

DEA has not said which highway the stop happened on. The agency also has not said the exact date. DEA has not said if anyone was arrested or charged in this stop. The case is still open.

The DEA's McAllen office is part of the DEA Houston Field Division. That division covers 131 counties across South, Central, and Southeast Texas. DEA agents often work with DPS troopers on South Texas highways. Together they look for drug loads and hidden cash tied to smuggling.

This is not the first big cash or drug bust in the area this year. In March, DPS troopers found $83,855 in cash on US Highway 281 in Hidalgo County. In June, DPS troopers found 30 bundles of cocaine in Brooks County. Agents said that cocaine was worth about $780,000. Also in June, U.S. Border Patrol agents seized more than $570,000 in cash. That seizure was part of a broader push against smuggling in the region.

South Texas sits along major smuggling routes. Highways like US 281 and US 83 carry both legal freight and, agents say, hidden drug loads and cash. DPS and DEA run regular patrols and checkpoints looking for both.

Federal law makes it a felony to hide cash and move it to dodge reporting rules, if the amount is over $10,000. That is called bulk cash smuggling. It can mean up to 5 years in prison. The government can also keep the money. That is called asset forfeiture.

Texas law treats big cash tied to crime even more seriously. Moving $300,000 or more in criminal proceeds is a first-degree felony in Texas, the most serious felony class. It can mean 5 to 99 years, or life, in prison.

No one has been named or charged in this specific stop. DEA has not confirmed any arrest tied to the seizure. The agency has not said if state or federal charges will follow.

Cases like this often move slowly. Agents test and count the cash. They also check it against drug task force records and past cases. A civil case to keep the money can move forward even if no one is ever charged with a crime.

In 2021, a separate multi-agency operation in South Texas led to 19 arrests and more than $500,000 seized. That case is not connected to this seizure. It shows these South Texas highways have drawn major drug money for years.

DEA has not released more details on this stop. El Tejano will update this story if the agency names anyone or announces charges.
