ENID, Okla. (AP) -- An employee who suffered severe burns when a grain elevator exploded last month has died of his injuries.


Wayne Rivers was burned severely around his head during a fire and explosion at the ADM Milling Company plant in Enid on January 24th. He died Tuesday at the Integris Baptist Paul Silverstein Burn Center in Oklahoma City.


Enid Fire Marshal George Frye says Rivers was coming from an office in the plant's bulk receiving area when a fireball hit him and he was knocked down a metal catwalk 25 feet into the basement.


Officials have said flour dust likely ignited to cause the explosion, but no official cause has been determined.


The plant is currently operating, but is not back to full production levels yet.
