MOORHEAD – What's 9 times 12? The number of graphing calculators police seized from a Las Vegas woman's car during a traffic stop last week, according to court documents.

Antesha Smith, 23, was pulled over the afternoon of Thursday, April 14, in south Moorhead for having a license plate registered to a different car, and Moorhead Police Officer Joe Brannan searched her vehicle after discovering that the other car had been stolen, documents said.

In his search, Brannan found 108 Texas Instruments graphing calculators and an "Alpha Alarm" stick, which is a security device used at check-out to deactivate the alarm on purchased items.

Smith told Brannan she purchased the graphing calculators out-of-state and was planning to sell them for a higher retail value in Las Vegas, documents said.

Smith was arrested and taken to the Clay County Jail on felony charges of receiving stolen property, possession of burglary or theft tools, and bringing stolen goods into the state, documents said.
