Warnings Robert Card was ‘hearing voices’ and ‘going to snap’, before Maine mass shooting

The family of a man who carried out a mass shooting in Maine warned that he was hearing voices five months before he killed 18 people, officials have confirmed.

Documents released on Monday show it was one of a number of attempts to alert authorities to the danger Robert Card potentially posed.

In July, the firearms instructor, who was also a petroleum supply specialist and Sergeant First Class in the US Army reserve, spent two weeks in a psychiatric hospital before being released.

Around three months ago, Card tried and failed to buy a silencer from a gun shop owner who feared he might pose a danger to others.

And a deputy from the Sagadahoc County Sheriff’s Office went to Card’s home after a soldier from his reserve unit told them he feared Card was “going to snap and commit a mass shooting” because he was hearing voices again.

The officer made numerous attempts to find Card but could not locate him.

The sheriff’s office was also told he was a firearms instructor and had access to weapons.

Papers published by the sheriff revealed that Card, 40, also avoided detection by police, the FBI, and the government, despite numerous warnings about his mental health and weapons skills raised over a period of around seven months.

Eventually, a state-wide alert was issued to warn authorities that he was known to be “armed and dangerous”.
