Hidalgo County jail records show the driver, Reyes R. Hernandez III of Humble (UHM'-buhl), was being held Tuesday on charges of money laundering and unlawful carrying of a weapon.
No attorney was listed for the 31-year-old Hernandez, whose bond was set at $100,000 following last Thursday's stop on southbound U.S. 281.
The Texas Department of Public Safety says a 27-year-old passenger, Daniel Carrillo of Houston, was arrested on a money laundering count. Jail records did not list him as still in custody.
A trooper had stopped the SUV for a traffic violation. The bundles of cash were in a tire.
A DPS spokeswoman said no further details were available.
