A gunman wearing paper clothes and a bandana is on a robbery spree in Cheatham County.The unidentified man robbed a BP Station off Interestate-24 in Joelton last week, and struck again at a Shell Station half a mile away Monday morning.Video surveillance obtained by Nashville's News 2 Investigates shows the gunman bursting into the Shell Station wearing a white paper shirt, pink paper pants and white bandana.He quickly points his semi-automatic pistol at the clerk, who chose not to be identified, demanding cash.The clerk, a mother of two, remained calm albeit being faced with terror."Give me all the money is what he said. He wanted me to open the till and I just backed up and let him open it," she told Nashville's News 2 Investigates."And now he wants me to get down. I said okay. Now he's looking back and he drops some money by the door," the clerk continued.When asked why she was not afraid, the clerk said that she worked at a bank for six years."I was head teller. We had classes for all that stuff," she said.She added that she understand the mentality behind robberies.Detectives said that the robber is quite possibly a man who bought gas at the same station, from the same clerk, 15 minutes before committing the crime.The clerk said that she knows 100% it was the same guy.Besides noticing that the robber had the same car as the previous customer, the clerk said she also noticed that he had the same shoes.The suspect's car is a green Ford Taurus with a license plate that possibly starts with 162.He is described as a black male around six feet tall wearing disposable paper clothes.When asked what message she would give to the robber, she replied, "Get a job. He'd make more money the honest way than robbing people."The armed robber has hit two stores within a half mile in less than two weeks off I-24 in Joelton.Anyone with information is urged to contact the Cheatham County Sheriff's Department at 615-792-4341.
