MOORE, Okla. — First responders are racing against time in the search for any survivors after a devastating tornado ripped through Moore, Oklahoma Monday afternoon.

Hopes were lifted Tuesday after the medical examiner revised the death toll to 24.

As the search effort shifts from rescue to recovery, stories of survival and heartache are emerging from the debris.

On Wednesday, Secretary of Homeland Security Janet Napolitano travels to Oklahoma. 

She will meet with state and local officials where she will make sure that first responders are receiving the assistance they need.
