Mayfield candle factory "looks as if a bomb has dropped on it," mayor says after tornado hit

The mayor of Mayfield, Kentucky, said a candle factory in her city where dozens of people were trapped amid severe weather "looks as if a bomb has dropped on it."

"We hope there are still rescues to be made," Kathy Stewart O'Nan told CBS News' Lana Zak on Saturday. "We fear that it is now just recovery."

There were 110 workers in the factory — Mayfield Consumer Products — when a tornado hit the area as part of a wider storm system that lashed the central U.S. overnight. O'Nan said the building has "completely collapsed," and officials said about 40 people have been rescued.
