SAN ANTONIO -- A manager opened fire on two men police said were trying to rob a convenience store Monday night on the city's Southwest Side.

Police said that Joe Raymond Galindo, 19, entered Billy's Foodmart in the 1400 block of Brunswick Avenue at 9:30 p.m. and pulled a gun on the clerk.

Seconds later, the clerk got a gun and fired five rounds, police said.

Galindo was hit in the arm. Twenty-two-year-old Paul Martin Luevano, who was standing guard outside the front door, suffered a superficial wound to his hand, police said.

According to authorities, the men ran to a getaway car, where three female accomplices were waiting.

The five later showed up at Southwest General Hospital for treatment and were arrested.

They were charged with aggravated robbery with a deadly weapon.
