CHICAGO - A string of violent storms blew through the US Midwest and South on Friday, killing at least 32 people in four states.

And the death toll could rise as daylight broke Saturday on the search for survivors, according to a report Saturday on the CNN.

The twisters splintered homes, damaged a prison and tossed around vehicles across the region, leaving at least 15 people dead in southern Indiana, another 13 in Kentucky, three more in Ohio, and one in Alabama, officials said.

Friday's carnage came two days after an earlier round of storms killed 13 people in Kansas, Missouri, Illinois and Tennessee.

Saturday started with large swaths of the South still battered by heavy rain and parts of western Florida, southern Georgia and southern Alabama remaining under tornado watch.
