Authorities in central Illinois are investigating after a 31-year-old worker died in an apparent accident at the Archer Daniels Midland Co. corn processing plant in Decatur.

The Macon County coroner identified the worker as Michael Cordray of Decatur. The Bodine Services employee was in the process of cleaning the interior of a tank at the time of the accident.

In a statement, ADM spokeswoman Jackie Anderson says the man fell while working in a confined space at the plant.

Coroner Michael Day says Cordray was pronounced dead Wednesday evening at the ADM facility. An autopsy is planned.
