Maryland police are looking for a woman who allegedly shot a gas station convenience store worker during an attempted robbery over the weekend. Surveillance footage inside the store shows the woman calmly walking up to the counter at a Shell station in Columbia around 7:43 p.m. on April 17 and producing a silver revolver from her purse, which she aims at the clerk off-screen while appearing to order the employee to open the cash register.
