LINCOLN, Neb. (AP) — Eastern Nebraska authorities say they seized $2.4 million in suspected drug money from a semitrailer after a traffic stop along Interstate 80.

The Lancaster County Sheriff’s Office says deputies pulled over the semitrailer a few miles west of Lincoln around 10:30 a.m. Thursday. The office says the deputies became suspicious of the driver and his passenger and then were denied permission to search the truck. A drug dog taken to the scene alerted deputies to the odor of drugs, so the big rig was searched.

The Sheriff’s Office says heat-sealed and banded cash that smelled of marijuana was inside several pieces of luggage that were found.

The two people were arrested on suspicion of violating drug laws. Online court records don’t show that they’ve been formally charged yet.
