A manhunt is under way after mass shootings in Lewiston Maine. State officials say at least 18 are dead -- all from gunshot wounds -- and 13 others are injured, with at least three in critical condition. Police say the shooter is a 40-year-old, military-trained firearms instructor who was recently committed to a mental health facility. He's still at large and considered armed and dangerous, and people in multiple cities are being told to shelter in place and lock their doors.
