At least one person was killed in a massive explosion at an Illinois silicone factory on Friday, May 3, authorities have confirmed.
Two more people, who are reported to be missing, are also presumed dead following the plant explosion.
The AB Specialty Silicone factory in Waukegan, which is nearly 50 miles north of Chicago, was hollowed out on Saturday, May 4.
The rescue teams started a search operation for two missing workers due to concerns over the remaining structure's stability.
Officials recovered the dead body of one employee. Four more employees were rushed to the hospital with injuries from the explosion.
According to Waukegan Fire Marshal Steven Lenzi, it's unlikely that the two missing people survived the explosion.
Lenzi said, "The conditions are really rough in there. There's a lot of damage. There was a lot of fire throughout."
Rescue teams were called off but they would not able to resume the search until the remaining structures of the plant are torn down.
Investigators have yet to determine the cause of the explosion. The factory mixes chemicals and other materials to make silicone.
At least five buildings nearby reportedly were damaged.
