A security guard was killed and a gunman was shot dead by a state trooper in a shooting incident at the New Hampshire Hospital in Concord on Friday. The attacker has been identified as John Madore, a transient who had previously lived in the area. Authorities say Madore used a 9mm handgun to shoot Bradley Haas, who was working security at the hospital's front lobby entrance. Haas, a former police chief and Army veteran, died protecting patients, staff, and visitors. New Hampshire Attorney General John Formella praised Haas as a hero and expressed condolences to his family.

The state trooper who killed Madore has not been identified as the investigation is ongoing. However, authorities have lauded the trooper's actions as heroic and credited them with saving a lot of lives. The motive behind the shooting is still under investigation.

After the shooting, authorities investigated a suspicious vehicle on the hospital's campus, a U-Haul. The incident prompted a response from Governor Chris Sununu, who extended condolences to Haas's family and thanked law enforcement for their quick response to the scene. The shooting has prompted an outpouring of support and condolences from the community.
