Stunned Alabama searches for missing after tornado kills 23

First responders in Alabama continue to hunt for survivors after a devastating tornado killed at least 23 people, injured dozens more, smashed homes, snapped power lines and toppled a massive steel cell tower on Sunday. The tornado was part of a powerful storm system that also ripped through parts of Florida, South Carolina and Georgia. The area had been warned of possible tornadoes days before the storm, but Lee County residents only had warnings eight to nine minutes before the killer twister struck. Evidence indicated the storm roared through as an EF-4 in strength with winds of about 170 mph. At least three children – ages 6, 9 and 10 – have died. The tornado was the nation's most deadly since 2013.
