A gunman entered a shopping mall and began randomly opening fire on customers Monday night, killing six people and injuring many others before he was killed, police said. More than three hours later, police were searching stores for shocked shoppers and employees who were hunkered down awaiting a safe escort from the Trolley Square mall. "We have six fatalities and multiple victims at hospitals," police Detective Robin Snyder said. "They were found throughout the mall. I don't know male or female or ages." The two-story enclosed mall, just southeast of downtown, is a refurbished old trolley barn, with a series of winding hallways and about 80 stores.
