Three California men are being held on $1 million bond each after their arrest on suspicion of hauling more than two tons of marijuana across eastern Illinois.

Douglas County State's Attorney Kevin Nolan says Illinois State Police troopers arrested the men Monday night after finding 4,400 pounds marijuana in their semitrailer truck on Interstate 57 north of Tuscola. The town is about 30 miles south of Champaign.

Nolan says a drug-sniffing dog found the marijuana packed away among crates of vegetables.

Thirty-one-year-old Jesus Guzman, 35-year-old Eric Cabrera and 32-year-old Joshua Cornillez appeared at a bond hearing Tuesday. They are from the Livingston, Calif. area.

Nolan says the men haven't been charged yet. But he anticipates filing cannabis trafficking charges against them.
