On June 19th 1984 Dave Bocks began his shift at the Fernald Feed Materials Production Center. It should have been a regular day, with a routine assignment of fixing a meter and valve in the number 8 plant at the facility. Near the end of his shift Dave was seen, for a final time, by a coworker. He would never be seen again. Only a few traces were left behind, including a crusty residue left in one of the plants furnaces.
