In Aurora, Illinois, a gunman went on a shooting spree Friday, killing five and wounding six others. Forty-five-year-old Gary Martin opened fire on his co-workers at water valve manufacturer Henry Pratt Co. after learning of his termination. The gunman, who was later killed by police fire, had worked at the company for 15 years. Martin had previously been convicted and served time for violence against a former girlfriend, including hitting her with a baseball bat and stabbing her with a knife. Police say Martin’s Smith & Wesson handgun was not legally obtained but that he did manage to obtain a firearm owner ID card despite having a felony record.
