LARGO — Police have arrested a man suspected of robbing a convenience store here last month. Paul Andrew Wheeler identified himself as the robber and said he committed the crime because he was using crack cocaine the day of the robbery, police say. According to police here's what happened: On Dec. 15 at around 4:25 p.m., Wheeler, 44, entered the Kwik Stop Food Mart at 12691 Seminole Boulevard and demanded money from the clerk while keeping one hand in his jacket pocket, as if he was holding a weapon. Police received a tip and tracked down Wheeler, who identified himself as the man in a surveillance video that captured the crime. Wheeler was arrested Thursday on a charge of strong arm robbery.
