'Body Worlds' Exhibit to Stop Using Cadavers From China

The doctor behind a museum exhibit of preserved human bodies says he won't be using cadavers from China.

Gunter von Hagens tells ABC's "20/20" that he's had to destroy some of the bodies he'd gotten from China because they had injuries suggesting they were victims of execution.

The exhibit, "Body Worlds," show preserved bodies in various poses, like playing poker or throwing a football.

The doctor invented a liquid plastic process to preserve the cadavers.
