To add, all they apparantly found of Kraft was part of a finger.
The joke at the time was “Why did Richard Kraft feed Helana through the woodchipper feet first”? “So he could see the look on her face.”
Although there was never any evidence that she was still alive, let alone conscious, when fed in. Heck, Richard Kraft was so thorough that the rental place’s testimony that they’d never had a woodchipper returned so clean was a major piece of evidence.
Like those Iraqi mobile bioweapons labs... all freshly sanitized and painted.
