Gov. J.B. Pritzker issued a disaster proclamation after a dozen tornados tore across Illinois Friday night, killing a man after a roof collapsed at a packed concert venue in Belvidere, outside of Rockford, and killing three more in downstate Crawford County.

Pritzker signed the proclamation late Saturday, allowing the state to send assistance to DuPage, Boone, Crawford, Marion and Sangamon counties.

“The devastating storms that swept through our state last night have upended communities and resulted in heartbreaking injury and loss of life,” Pritzker said in a statement.

The severe weather was part of a system that tore through the South and Midwest, killing at least 27 people in total across Illinois, Indiana, Tennessee, Arkansas, Alabama and Mississippi.

Pritzker visited the destruction in Belvidere on Sunday, where an EF-1 tornado hit with winds as high as 100 mph, collapsing the roof the Apollo Theatre as more than 200 people attended a heavy metal concert.

One concertgoer died in the rubble. He was identified as Frederick Forest Livingston Jr., 50.

Livingston was standing next to his son as the roof crashed down on him.

“I couldn’t save him,” his son, Alex Livingston, told ABC7-Chicago. “It happened so fast.”

Forty-eight people were taken to hospitals, Pritzker said. About half had been discharged by Saturday afternoon, but Pritzker said five remained in critical condition.

“I’m really grateful to the residents here in Belvidere and to the concertgoers and first responders who risked their lives on Friday night to pull people out of the rubble and wreckage,” Pritzker said Sunday.

“Lives were saved because of the quick work of the people who live here and work here.”

Meteorologists have confirmed 12 tornadoes hit northern Illinois and Indiana on Friday. The closest confirmed tornado near Chicago was an EF-1 that hit from Lombard to Addison, according to the National Weather Service.

In Crawford County, three people were killed and eight injured when a tornado hit near New Hebron, causing several roofs to collapse, authorities said.

It may take two to three more days to assess the damage across the state, Illinois Emergency Management Agency Director Alicia Tate-Nadeau told reporters Sunday.

The IEMA said tornadoes also caused damage in other several towns across the state:

• In Boone and Crawford County, around 30 buildings were damaged, including at Robinson Airport.
• In Sangamon County, a tornado damaged several buildings in Sherman, Riverton and Dawson.
• In Marion County, about a dozen homes and businesses were damaged In Addison in DuPage County, several buildings were damaged.

The National Weather Service said it will survey the destruction in the coming days to confirm if tornadoes also hit Batavia, Plainfield, Plano, Montgomery, Frankfort and Park Forest.
