The Texas Department of Public Safety says 23-year-old Bianca Dinora Mendez was stopped for a traffic violation Thursday on Interstate 40.
Her vehicle was searched and seven bundles of heroin allegedly were found hidden in the seats. DPS says the drug is valued at $2.7 million.
Mendez, a resident of Cypress, Calif., remains in the Carson County jail and is scheduled to be arraigned Friday. She's charged with a felony count of possession of a controlled substance.
DPS says Mendez was transporting the heroin from Los Angeles to Oklahoma City.
Jail records did not indicate an attorney for her.
