Maine Police Alerted Weeks Ago About Threats from Shooter on the Loose

Maine police issued a statewide awareness alert last month after receiving threats from Robert Card, the U.S. Army reservist suspected of killing 18 people in two mass shootings. The alert urged officers to be on the lookout for Card, who had allegedly threatened to shoot up the National Guard Base where he had trained. Despite extra patrols and efforts to locate him, Card was not found until recently when he was discovered dead in a tractor-trailer, having died from a self-inflicted gunshot wound.
