North Liberty police arrested a Colorado woman after allegedly finding 11 pounds of marijuana in her vehicle.

Alexandra Owens, 27, was charged Oct. 6 with failure to affix a drug tax stamp.

The complaint said officers pulled Owens’ car over on I-80 near the 238 mile marker because of a non-functioning headlight.

Owens allegedly appeared to be nervous and shaking when approached by officers and denied officer’s consent to search the vehicle.

A K9 later alerted police to the car, and a search yielded bags totaling approximately 11 pounds of marijuana without a drug tax stamp affixed, the complaint said.

Failure to affix a tax stamp is a Class D felony, punishable by up to five years in prison and a maximum fine of $7,500.
