Three men were arrested and more than 300 pounds of marijuana seized by Lancaster County Sheriff's deputies during separate traffic stops on Interstate 80 near Lincoln in February 2018.
The first stop occurred near the Nebraska 103 exit, according to an arrest affidavit.
A deputy pulled over an eastbound SUV for speeding and following too closely and asked to search the vehicle after developing an unspecified suspicion that "criminal activity was afoot." A police dog indicated it smelled the odor of drugs inside, the affidavit said.
Deputies found 98 packages of marijuana in boxes and a duffel bag in the rear hatch area, the affidavit said.
The driver, Doua Vu, 50, of Fresno, California, jailed on possession of marijuana with intent to deliver and no drug tax stamp.
Deputies two days later stopped two eastbound vehicles they believed to be traveling together: a car for following too closely and a truck for traveling over the shoulder line, the affidavit said.
The truck driver, Ariel Hernandez of Chicago, had THC concentrate in the cup holder, investigators said.
The deputy, believing the 27-year-old was involved in criminal activity, searched the truck and found seven duffel bags containing 134 pounds of marijuana and 2,150 THC vapor-pen cartridges, the affidavit said.
Hernandez was taken to jail on suspicion of possession of marijuana with intent to deliver. The driver of the car, Samuel Colonna, 22, of Chicago, was jailed on suspicion of aiding and abetting possession with intent to deliver.
