Maine Police Alerted About Shooter's Threats, But Failed to Locate Him

Police in Maine were alerted last month about "veiled threats" made by Robert Card, the U.S. Army reservist who carried out the state's worst mass shooting. Despite increased patrols and a visit to Card's home, law enforcement officials were unable to locate him. The Army Reserve had previously tipped off local authorities about Card's threats, but it remains unclear if there was any follow-up. Card had a history of mental illness and had been committed to a mental health facility in July after making threats during a training exercise. The case highlights missed red flags and raises questions about what could have been done to prevent the massacre.
