Authorities were previously deployed to the alleged Maine shooter’s home, police said. 

Police said Monday that suspect Robert Card was visited by police multiple times before his death. The local sheriff’s department revealed they responded to Card’s home in May, due to family concerns over the man’s health, according to a press release. 

“Like many people, I’m breathing a sign of relief tonight knowing that Robert Card is no longer a threat to anyone,” Democratic Maine Gov. Janet Mills. “I also know that his death might not bring solace to many. But now is a time to heal.”

The family’s concern about Card’s mental health dated back to early this year before the sheriff’s office was contacted in May, according to the AP.

Card underwent a mental health evaluation last summer after he began acting erratically at an Army training facility in New York, officials said. A bulletin sent to police shortly after last week’s attack said Card had been committed to a mental health facility for two weeks after “hearing voices and threats to shoot up” a military base.
