WYNNE, Ark. — Unrelenting tornadoes that tore through parts of the South and Midwest killed at least 11 people, collapsed the roof of a packed theater during a heavy metal concert in Illinois, and left small towns and big cities throughout the region bewildered Saturday by the damage.

Tornadoes touched down into the night, laying waste to homes and businesses and stripping bark and limbs off trees, as part of a sprawling storm system that also brought wildfires to the southern Plains and blizzard conditions to the Upper Midwest.

The dead included four in the small town of Wynne, Arkansas, Cross County Coroner Eli Long told KAIT-TV. Other deaths were reported in Alabama, Illinois, Indiana, Mississippi the Little Rock area.

Wynne City Councilmember Lisa Powell Carter said the town about 50 miles (80 kilometers) west of Memphis, Tennessee, was without power and roads were full of debris.

"I'm in a panic trying to get home, but we can't get home," she said Friday night. "Wynne is so demolished. ... There's houses destroyed, trees down on streets."

People rushed to lift the collapsed part of the ceiling and pull people out of the rubble, Gabrielle Lewellyn, who had just entered the theater, told WTVO-TV.

"They dragged someone out from the rubble, and I sat with him and I held his hand and I was (telling him) 'It's going to be OK.' I didn't really know much else what to do," Lewellyn said.

The venue's Facebook page said the bands scheduled to perform were Morbid Angel, Crypta, Skeletal Remains and Revocation.

The storms also killed three people in Sullivan County, Indiana, Emergency Management Director Jim Pirtle said in an email. Some residents were missing in the county seat, Sullivan, near the Illinois line about 95 miles (150 kilometers) southwest of Indianapolis.

In the Little Rock area, at least one person was killed and more than two dozen were hurt, some critically, authorities said.

The tornado in Little Rock tore first through neighborhoods in the western part of the Arkansas capital and shredded a small shopping center that included a Kroger grocery store. It then crossed the Arkansas River into North Little Rock and surrounding cities, where widespread damage was reported to homes, businesses and vehicles.

Little Rock resident Niki Scott took cover in the bathroom after her husband called to warn her of a tornado. She could hear glass shattering and emerged to find that her house was one of the few on her street that didn't have a tree on it.

"It's just like everyone says. It got really quiet, then it got really loud," Scott said afterward, as chainsaws roared and sirens blared.
