The fourth body found on the site of the factory in Illinois destroyed by an explosion

WAUKEGAN, Ill. (AP) – Teams found the body of another victim of an explosion in a silicone factory in northern Illinois, killing four people.

Waukegan Fire Marshal Steve Lenzi said the body was found in the rubble of the AB Specialty Silicones factory in Waukegan, about 50 kilometers north of Chicago. The identity of the victim was not disclosed.

The Lake County Coroner's Office on Tuesday identified two of the victims of Friday's explosion: Jeff Cummings, 57, of Kenosha, Wisconsin, and Byron H. Biehn, 53, Township of Brighton, Wisconsin. Officials have previously identified a third victim: Allen Stevens, 29, of Salem, Wisconsin.

Lake County Coroner Howard Cooper announced that an autopsy of the fourth victim would be scheduled for Thursday.

Lenzi said that there was no evidence of a criminal offense and that the blast seemed to be the result of an accident occurring in the factory processes.
