Scientists May Have Found Medici Murder

Undated photo released Wednesday Jan. 3, 2007 by Prof. Donatella Lippi of the University of Florence, shows materials, viscera (remains of human liver) and two crucifixes, found in the Santa Maria Bonistallo church crypt, in Poggio a Caiano near Florence, central Italy. Scientists in Italy believe they have uncovered a 400-year-old murder. Historians have long suspected that Francesco de' Medici, Grand Duke of Tuscany, and his second wife Bianca Cappello did not die of malaria but were poisoned -- probably by Francesco's brother, Cardinal Ferdinando de' Medici, who was vying for the title -- but that theory was never proven. Now, forensic and toxicology experts at the University of Florence believe they have found evidence of murder, according to their study, which was published in the British Medical Journal on Dec. 21.

(AP) -- Scientists in Italy believe they have uncovered a murder - 400 years after it is thought to have taken place. Historians have long suspected that Francesco de' Medici, Grand Duke of Tuscany, and his second wife, Bianca Cappello, did not die of malaria but were poisoned - by Francesco's brother, Cardinal Ferdinando de' Medici, who was vying for the dukedom. For four centuries that theory remained just that - a theory.
