The Orange County Sheriff's Office said it happened just before 10 p.m., when a deputy pulled the women from California over on I-40 East near Mebane for a routine traffic violation.
During the course of the investigation, the deputy asked for assistance from a Mebane Police Department K-9 unit. After arriving, the dog alerted to the odor of illegal drugs in the trunk of the car. When officers opened the trunk of the Toyota Camry, they found 130 pounds of marijuana packed inside.
The driver of the Camry, Ruth Paez Diaz of San Jose, California and her daughter Briann Marie Diaz of San Francisco, California were each charged with two counts of trafficking marijuana and are in the Orange County Detention Center under a $100,000 secured bond.
The women will appear in court later this month.
