A former employee of a Casper adult store is now admitting her role in a robbery at the business.

Twenty-Five year old Casey Bingemer has changed her plea to guilty on one charge 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 part of a plea deal, prosecutors will seek no more than a nine-to-fourteen year prison sentence.

She remains jailed on fifteen-thousand dollars bond and will be sentenced at a later date.
