An Army investigation into Army reservist Robert Card, who killed 18 people in Maine last year, revealed significant lapses and communication failures within his unit and between military and civilian authorities. Three officers were disciplined for dereliction of duty for failing to act on multiple warning signs about Card's deteriorating mental health and potential for violence. The findings prompted Maine's congressional delegation to call for stronger cooperation between the military and local law enforcement, as well as enhanced gun control measures. Victims' families and their attorneys are seeking more information about Card's discharge from a civilian hospital and how the military handled his mental health care. Affected families and legal representatives emphasize the need for accountability and systemic changes to prevent future tragedies. The investigation has led to calls for improved procedures and legislative action aimed at preventing similar incidents.
