Nearly one ton of marijuana was discovered Wednesday during a traffic stop on Interstate 80, the largest drug bust ever made by the Douglas County Sheriff's Department.

"I was patrolling Interstate 80 near my area and observed a vehicle with an equipment violation and conducted a traffic stop," says Douglas County Sgt. Ed Van Buren.

That vehicle was a pickup with a camper on top and Utah license plates, one of which was partially covered. The truck was heading eastbound on I-80 when it was stopped at 96th Street around 1 p.m.

"While speaking with him, I detected some things that made me suspect that there may be criminal activity occurring, so I asked for consent to search and was denied," says Sgt. Van Buren.

That's where Rocky the canine came in to sniff out a multi-million dollar discovery. "Rocky indicated the odor of drugs coming from the rear of the camper."

That gave Sgt.Van Buren probable cause to search inside and what he found surprised even him. "Yeah, a little bit. I didn't expect that much."

"From the search we found 93 bundles of marijuana totaling 1,930 pounds," says Douglas County Sheriff Tim Dunning.

“Most of 'em were wrapped in plastic, others were wrapped like they were Christmas presents." All with an estimated street value of $3 million.

“As far as one of this size, I believe this was the largest one that the sheriff's office has ever had," says Sheriff Dunning.

“That was our first traffic stop of the day and our only traffic stop, so yeah, that was a pretty good day's work," says Sgt. Van Buren.

The driver of the pickup, 28-year-old Stanley Suojanen of Pleasant Grove, Utah, was arrested on a charge of felony possession with intent to deliver marijuana and faces up to 20 years in jail.

The case now goes to the Douglas County attorney and the U.S. attorney.
