A union steelworker died Saturday at the U.S. Steel mill in Granite City. The company issued a statement that says, "There are no words that can capture the grief we feel for our colleague and their family, friends, and co-workers." It goes on to say that the company will cooperate fully with all investigations into the matter. A steelworkers union official says they were told the death happened due to a high-voltage flash in the cold mill part of the facility.
