KANSAS CITY, Mo. -- Police were investigating an accidental shooting at the Kansas City Health Department Friday. Health Department spokesman Jeff Hershberger said a gun in a woman's handbag discharged when she set the bag down Friday morning in the atrium. The first bullet grazed a patron in the leg. Paramedics treated and released the victim at the scene. The gun discharged a second bullet as the woman's companion carried the bag out of the building. That shot didn't hit anyone. Witnesses gave descriptions of the two after they fled the scene. "It could have been worse," Hershberger said. "I was very happy and satisfied with our security response. They immediately had somebody over there offering assistance. They had somebody calling 911. They had somebody tracking the person with the security camera as they ran out of the building. We were able to provide descriptions to the police of what was going on. We had somebody contacting our EMS that we have housed here in the building to make sure there was assistance to everyone." Kansas City has plans to upgrade its detection system at sites such as the Health Department pending a citywide security assessment. The atrium's customer service department reopened shortly after the incident.
