Pathologist finds answers to medieval mysteries

French pathologist Philippe Charlier has used high-tech imagery and DNA analysis to answer questions about Joan of Arc, Napoleon, and a mistress of King Henri II of France. He is now turning his attention to Richard the Lionheart.

Charlier is analyzing a small sample of Richard's heart tissue. He hopes to find out more information about what killed him, along with information about the 12th century embalming process.
