Maine Gunman's Disturbing Warning Signs Before Mass Shooting

Army reservist Robert Card, responsible for Maine's deadliest mass shooting, had exhibited concerning behavior and made threatening statements months before the shooting. He had expressed paranoia and concerns about fellow soldiers talking behind his back, and had been warned about his deteriorating mental health by family members and fellow reservists. Despite these warnings, he was not taken into protective custody, and the shooting at a bowling alley and a bar in Lewiston resulted in 18 deaths and 13 injuries before Card died by suicide.
