DELRAY BEACH, Fla. -

Authorities say two customers at a South Florida grocery store were shot and killed by two masked men with semi-automatic handguns.

Police say two men with bandanas over their faces opened fire early Sunday inside Community Market.

One of the two victims shot died at the scene and the other was taken to Delray Medical Center's Trauma Unit. Officials said that victim later died of his injuries.  The names of the victims were not released on Sunday.

Witnesses told police that two armed men who had their faces covered had entered the store and immediately began firing semi-automatic handguns all about the store. Investigators said the robbers shot at employees and customers.

Police said the men demanded cash from the register and pistol whipped an employee as he tried to open the register. Officers said the men were able to escape with an undetermined amount of cash.

According to police, the first man is described as black, about 5-feet 6-inches to 5-feet 8-inches tall with a thin build. He had a dark jacket with a dark hat with a red bill, as well as a white T-shirt and long dark pants. Witnesses said he was also wearing dark shoes with light-colored soles and a bandana on his face.

The second robber was described as black, slightly taller than the first man, with a light gray jacket and dark shorts that reached below his knees. He also had a bandana on his face.

Police said both men are armed with semi-automatic handguns and should be considered dangerous.

Delray Beach Officer Jeffrey Messer says that the robbery is similar to one that took place two blocks away on Saturday.

Anyone with information on these crimes is asked to contact Detective Joseph Hart at 561-6220, or Crime Stoppers at 800-458-TIPS.
