A former employee of a Casper adult store is going to prison after admitting her role in a robbery at the business.

Twenty-five year old Casey Bingemer was sentenced to nine-to-fourteen years at the Wyoming Women's Center in Lusk, after pleading guilty on one count of conspiracy to commit aggravated robbery at the Emporium adult store on East F street in Casper.

Investigators say in late December, Bingemer and her boyfriend Antoine Miller, went to the store, and miller pulled out a black semi-automatic gun and took a bank bag.

They also say Bingemer was wearing a mask at the time of the incident.

The owner of store told investigators that Bingemer had been fired earlier in the month, and could tell by looking at security video that it was her, based on the way she moved, and also knew that Miller was her boyfriend.

As for Miller, he has pleaded guilty to aggravated robbery and is waiting to be sentenced.
