A woman has pleaded guilty to attempting to smuggle more than $930,000 in cash across the Arizona border and into her native Mexico.

Federal prosecutors say 25-year-old Judith Angelica Ayala-Partida pleaded guilty Wednesday in U.S. District Court in Tucson to bulk cash smuggling.

She's scheduled to be sentenced Oct. 4.

Authorities say Ayala-Partida was driving a vehicle that was stopped last Nov. 16 at the port of entry in Nogales, Ariz.

She told U.S. Customs and Border Protection officers that she didn't have more than $10,000 to declare. But a currency-detecting dog alerted authorities to the driver's side quarter panel of the car and a search led to the discovery of 101 packages containing $937,188.
