NASHVILLE, Tenn. (AP) — Tennessee Highway Patrol officers found more than $4 million in cash hidden in cases of bottled water in a tractor-trailer that resulted in the arrests of two California men.

According to a news release from the highway patrol, the tractor-trailer was stopped on Saturday on Interstate 40 in Cumberland County. Using search dogs, authorities found duct-taped bundles of cash inside the bottled water cases in the trailer.

Department of Safety and Homeland Security Commissioner Bill Gibbons said in a statement Wednesday that I-40 is one of the top corridors for drug trafficking in the nation.

Federal authorities charged 42-year-old Armando Guzman of Moreno Valley, Calif., and co-driver 44-year-old Francisco Javier Cruz of San Jacinto, Calif., with interstate travel with intent to promote a drug trafficking conspiracy.
