Police said the 27-year-old female store clerk told them that the lone robber entered the station, pointed a handgun at her and demanded a gold chain she was wearing.
The clerk tried to give the robber change from the register, but he lunged at her and ripped the gold chain from around her neck, police said. He fled on foot with the jewelry.
