SIERRA VISTA, Ariz. -- A garbage truck was stopped carrying more than two tons of marijuana north of Huachuca City, a Department of Public Safety official said.
The truck had been driving erratically late Tuesday, said DPS Sgt. Steve Tritz.
"It got my attention," Tritz said. "He was driving slow and failing to signal."
The driver, who identified himself as 28-year-old Brian Rivera Martinez, said he didn't know how to drive the truck.
When a drug-sniffing dog arrived, it alerted authorities to possible narcotics. DPS officers found 4,112 pounds of marijuana bundled in the area where trash would be carried.
Martinez and passenger, Michael Trejo Duran Sr., 38, were arrested on suspicion of transporting and possessing marijuana for sale.
