The Lonesome Death of Hattie Carroll

If you're exactly like me you've been wondering - just in the last few days in fact - whatever happened to William Zantzinger, the killer in the great Bob Dylan protest song "The Lonesome Death of Hattie Carroll" (note the superb lyrics to this hypnotic song). I'd even done the math to figure that he'd still possibly be alive. Ian Frazier answers my questions.
