It’s flu season, and someone appeared to use that as a tactic while robbing four Henry County businesses since October, police said.

In each robbery, the man covered his face with what looks like a tissue or towel, Channel 2 Action News reported.

Then he showed the employees a gun in his waistband and asked for cash.

“He probably has just a napkin over his face indicating it’s the cold season, indicating he might have a cold,” Maj. Mike Ireland of Henry County police said.

In the robbery of the Metro PCS store on West Fairview Road, the man followed frightened employees to the back, then forced one to fill a bag with cash, Channel 2 reported. He also has hit two Dollar General stores and a Family Dollar store, according to police.

Investigators think someone will recognize him, even though his face is covered.

“If they have an idea or think it might be somebody,” Ireland said, “we’re asking them to call Henry County police and we’ll follow up.”
