Tombstone, Arizona - A Tucson Sector Border Patrol agent from the Willcox Station conducted a vehicle stop on a sedan traveling north on State Route 80 near Tombstone early Wednesday, resulting in the arrest of a United States citizen and three Mexican nationals.

When the agent stopped a Kia Forte for an immigration inspection north of the immigration checkpoint, he saw three people attempting to conceal themselves on the vehicle’s floorboard and back seat.

During questioning, the agent identified three males as Mexican nationals illegally present in the U.S. The driver, a 54-year-old Tucson woman, was arrested for human smuggling. The men will be processed for immigration violations, in accordance with Tucson Sector guidelines.
