ST. MARTIN, Mississippi -- A Dollar General store on north Washington Avenue in the St. Martin community was robbed at gunpoint Saturday night and investigators believe it may be related to a similar crime at a Dollar General in D'Iberville in December, according to Jackson County Sheriff Mike Ezell.

In Saturday night's incident, the suspect -- described as a tall, black male, about 20-23 years of age, with a slender build and dressed entirely in black -- entered the store, brandishing a weapon and demanding money. During the course of the robbery, he fired shots, striking one employee.

Investigators believe the suspect left the scene in a waiting vehicle.

A store employee said Monday her female co-worker had been struck in the arm and she was "doing good." The store is located just outside the entrance to The Reserve at Gulf Hills apartment complex and adjacent to a Family Dollar store.

Anyone with information on either crime is asked to call the Jackson County Sheriff's Department at 228-769-3063 or Mississippi Coast Crime Stoppers at 877-787-5898.
