OK Fire Chief "98 Percent Sure" There Are No More Tornado Casualties

Death toll at 24, including nine children

Rescuers have searched every home in devastated Moore, Okla., and the fire chief said he is "98 percent sure" there are no more bodies or survivors in the rubble of the Oklahoma City suburb devastated by what has now been rated an EF-5 on the weather scale, a ranking reserved for the deadliest and rarest of twisters. 

Word that the tornado had been classified as the most devastating funnel cloud punch Mother Nature can deliver came as the death toll held steady at 24, including nine children. The ranking, on the Enhanced Fujita Scale, puts the tornado in the same class as the deadliest in U.S. history, which hit Joplin, Mo., in 2011, killing 158 and injuring hundreds more.
