Slideshow: The person who was shot was breathing and alert and was taken to St. Vincent Hospital in serious condition, police said, but he later died. The man's name wasn't immediately released.Investigators said a man came into the store and approached a female worker in the doorway, putting something to her back that she thought was a gun and demanded money."The suspect then forced the victim to the office area, where he encountered a second employee who fired a weapon at him, striking him in the face," Indianapolis police Sgt. Linda Jackson said.Police said they think three or four shots were fired.Customers scrambled to the back of the store in what was described as a chaotic scene."I heard, 'bam, bam, bam.'
