BROWNSVILLE, Texas — Authorities are investigating three women from Dalton, Ga., after they say the women were caught trying to enter Mexico while carrying a combined $1.5 million in cash in their luggage.

The San Antonio Express-News reports that the seizure happened Wednesday at the Hidalgo/Reynosa International Bridge at Brownsville, Texas.

It is illegal not to declare cash when carrying more than $10,000 into or out of the United States.

The women’s names were not given. They were identified as being two U.S. citizens, ages 22 and 35, and a 55-year-old Mexican citizen.

They have been turned over to U.S. Immigration and Customs Enforcement-Homeland Security Investigations.
