Authorities looking for three missing workers after a blast and fire in a silicon factory in Illinois reportedly salvaged a body.
The other two workers are believed dead, and Waukegan's firestorm Steven Lenzi said on Saturday, the search for their bodies were suspended out of concern for the stability of the structure, the Chicago Sun-Times and other media reported.
The explosion at AB Specialty Silicones Friday shook the homes around the Waukegan plant, about 50 miles north of Chicago.

At the time of the explosion, nine employees were employed. Four were injured and two others refused medical treatment.
"The conditions there are really tough," said Lenzi. "There is a lot of damage, there was a lot of fire everywhere."

Lenzi said the cause of the explosion was undetermined and it could take days until the crews could continue their occupation search because heavy piping and other materials that were within the 30,000 foot structure pose a threat to firefighters and investigators.
He said the plant would normally operate 24 hours a day, mixing chemicals and other materials to make silicone.
The state fire marshal investigates together with the labor protection authority.
Residents in the area said they heard the explosion and shook their homes. Lenzi reported that five nearby buildings had been damaged and glass windows on windows and doors were broken.
Nancy Carreno, who lives near the factory, told the Chicago Tribune that the explosion did not break windows, but it was loud. She said the electricity flickered, then it came back on.
