Authorities in Lewiston, Maine, are searching for a US Army reservist who killed 18 people and injured 13 in a mass shooting at a bowling alley and a bar. The suspect, Robert Card, is considered armed and dangerous. Schools, doctor’s offices, and grocery stores closed as the state of Maine was gripped with fear. President Joe Biden ordered all US flags to be flown at half-staff, and condolences poured in from across the nation. The suspect underwent a mental health evaluation in mid-July after displaying erratic behavior. The motive for the shooting is still unknown.
