Deputies became suspicious of the truck when a K-9 alerted to the trailer, the post says. Deputies searched the tractor trailer and discovered the cash wrapped in plastic in the barrels. The money is believed to have been obtained from drug sales throughout the region and was headed to Mexico, Sheriff Alan Norman said.
“It's one of the largest U.S. currency seizures in Cleveland County history,” Norman told The Shelby Star. The Department of Justice has been called to assist in the investigation, according to the sheriff's office.
