Police were alerted just last month about a Maine shooter’s threats. ‘We couldn’t locate him.’

Police across Maine were alerted just last month to “veiled threats” by the U.S. Army reservist who would go on to carry out the worst mass shooting in the state’s history, one of a string of missed red flags that preceded the massacre. Two local law enforcement chiefs told The Associated Press that a statewide awareness alert was sent in mid-September to be on the lookout for Robert Card after the firearms instructor made threats against his base and fellow soldiers. Sagadahoc County Sheriff Joel Merry, whose jurisdiction includes Card's home in Bowdoin, said the Army Reserve tipped his department in September to the reservist's threats, and the sheriff sent the awareness alert to every law enforcement agency in the state after his deputy came back empty-handed from a welfare check to Card’s home.
