Police said Ayala seemed nervous and "verbally aggressive" with officers and refused to allow them to search her 2013 Dodge Avenger, CNN reported. Police called for Emma, a drug detection dog with the department's K-9 unit, and the dog indicated the presence of narcotics in three large jugs stored in the vehicle's trunk.
The jugs, which originally contained engine degreasing product Purple Power, were found to contain 75 pounds of liquid methamphetamine, worth an estimated $2 million on the street, police said.
Police said Ayala admitted she was delivering the drugs to Dallas in a deal coordinated by an unidentified man near her Laredo home. She said she previously made a similar delivery to Carrollton that was organized by the same man.
Ayala was ordered held without bond and is facing federal drug trafficking charges, police said. Her preliminary detention hearing is scheduled for Friday.
