O'Fallon Police have released a photo of the woman who robbed a fast food restaurant Tuesday morning at gunpoint and issued a reward for information that leads to her arrest.

"We're still looking for information and hope that someone will see the surveillance pictures we were able to obtain and recognize the suspect," Lt. Mick Hunter said.

The reward, which comes through the Crime Stoppers organization, is $1,000.

According to Hunter, a black woman with a thin build who is about 5-foot-5 came into the Hardee's at 110 E. Highway 50 just before 6 a.m. Tuesday, displayed a small black semi-automatic handgun and demanded money. The robber was wearing all black including a hooded sweatshirt, coat, and a scarf over her face.

The woman fled the store on foot. According to police, she is believed to be an experienced robber.

"She certainly did not appear to be in any hurry," Hunter said. "She was very casual about it. It was almost like she knew her way around."

It created a bit of a stir among residents that officers were seen at the McDonald's across the street shortly after the Hardee's robbery.

But Hunter said officers were there trying to retrieve security camera video to see if any shots captured the Hardee's suspect. Officers also checked other neighboring businesses for security video.

According to police, no one was hurt in the robbery. Hunter said it is unusual for a woman to commit that sort of crime.

Anyone with information about the case is asked to call the O'Fallon Police Department at 624-4545 or Crime Stoppers at 314-725-8403.
