WAUKEGAN, Ill. (AP) — Search and rescue personnel have located and are recovering the body of a third employee killed in the explosion and fire at an Illinois silicone plant.

Waukegan Fire Marshal Steve Lenzi tells a news conference that the body was located Sunday afternoon and personnel are in the process of recovering it.

He says one more body is believed to be located in the rubble of the plant, which was destroyed by the massive explosion and fire Friday night. He says that personnel still have about half of the building left to search.

The plant is owned by AB Specialty Silicones. Nine employees were in the building at the time of the blast. One body was found at the site early Saturday. A second employee died in the hospital later Saturday. The body found Sunday brings to three the number of confirmed dead. A fourth body is believed in the rubble. Of the remaining five, three were taken to a hospital. Lenzi says he does not have an update on their condition. Two others declined medical treatment.
