Morton police confiscated $672,000 found during a stop of an 18-wheeler on Interstate 20.
The money was in a tractor-trailer that a police officer chased six miles on I-20 west before stopping it at the Scott/Rankin county line.
Police Chief Nicky Crapps says officers believe the $672,439 is drug money.
Crapps would not identify the woman driving the truck or say what the charge against her is. She is from California and is in custody in the Morton jail.
Crapps said a Morton officer stopped the truck after seeing it driving erratically on the highway.
Officers found the cash, mostly in small bills, stashed in a compartment inside the truck cab. The truck was hauling dried peanuts.
Crapps says the truck was going to California from North Carolina.
