This part got me:
Late Tuesday night Raper was working at the Bar S plant in Lawton where he was in charge of cleaning the machinery.
“He slipped and went into the machine. He was still conscious at the time,” Ferris said. “So I can imagine the agony he was in, and he lost both of his legs in this accident.”
Ferris says it took about two hours to free Raper, but the trauma was just too much.
