U.S. Customs agents usually find drugs hidden in cars, but Monday brought a most unusual discovery at a Brownsville port of entry.
Agents said they found the driver's wife hidden in a vehicle.
She is in federal custody awaiting deportation.
Agents said they found the woman scrunched inside a wooden speaker box in the back seat of a Honda.
Agents arrested her husband, who is from Fort Worth, on alien smuggling charges.
