Colorado shooting victims: Store staffers, cop, photographer

  Three of the victims of a shooting at a Colorado supermarket were gunned down while putting in a day's work. Another was a police officer who raced in to try to rescue them and others from the attack Monday that left 10 dead. A picture of the victims began to emerge Tuesday, when the suspect in the killings was booked into jail on murder charges after being treated at a hospital. They included a magazine photographer, a Medicare agent with a passion for theater and others going about their days at a busy shopping plaza.
