A former CIA operative and Cuban exile plans to auction a lock of Che Guevara's hair, snipped before the Argentine revolutionary was buried in 1967. Gustavo Villoldo, 71, was involved in Guevara's capture in the jungles of Bolivia, according to unclassified US records and other documents. He plans to auction the strands of hair and other items kept in a scrapbook since the joint CIA-Bolivian army mission 40 years ago. "It's time for me to put the past behind and pass these on to someone else," said Villoldo, also a veteran of the ill-fated Bay of Pigs invasion of Cuba. Heritage Auction Galleries of Dallas will hold the auction Oct. 25-26. The scrapbook also includes the map Villoldo used to track down Guevara in Bolivia, photographs of Guevara's body, messages intercepted between Guevara and his rebels and a set of Guevara's fingerprints taken before his burial.
