South Dakota Highway Patrol troopers have confiscated 29 pounds of meth and nearly 7 pounds of cocaine after a traffic stop west of Rapid City. 

After a trooper stopped the car on a traffic violation on Interstate 90 Friday, a police service dog found a false
compartment in the rear cargo area. 

The Highway Patrol says 25-year-old driver Jese Hernandez Mendoza of Court Renton, Wash., and 32-year-old passenger Eddie Martinez of Los Angeles were arrested. 

Authorities estimate the drugs' street value is $664,000.
