Truck driver Guangyu Wu is charged with possession of marijuana and possession with the intent to distribute more than 25 pounds of the drug.

The 45-year-old man, from San Bernadino, faces nearly 22 years in prison if he’s convicted on both counts.

Warren County prosecutors say state police found the marijuana Tuesday during a commercial vehicle inspection in Greenwich. They say the drug was packed in 44 cardboard boxes and its estimated value is $5,145,000.
